    Hi all,

    I know this has been discussed before, but without clear resolution.

    CPR does not offer a trim kit to cover the 3/8" un-painted edges of the reproduction backglasses that they sell.

    The backglasses are beautiful ! Really nice work, but edge treatment is desperately needed.

    I have numerous sets of translite trim for standard translite glass.

    I have never had trouble installling trim and a translite.

    None of the standard trims fit correctly on this glass. It seems too thick for standard edge trim.

    People have successfully installed top trim and lift channels, but always lay off the side trim and consider it impossible.

    I have ordered system 11 trim from pinball life and it may be exactly what is needed even if a little friction tape is needed to secure it.

    I also ordered wpc-95 trim.

    Ill know more when it arrives.

    The problem is the rib/ridge inside of standard trims to allow for a translite.

    The rib/ridge is not needed in this application.

    I have 3 of these backglasses that will be installed at some point.

    What is the correct trim to install that will cover the edges and eliminate the light bleed that ensues?

    Whoa, that is a very wide gap...I don't think there is any trim that's going to cover that gap. Trim normally only sticks out from the edge a small fraction of an inch. Maybe 1/8" at most?

    The different types of trim are to accommodate the thickness of the glass, as well as the length of each edge of the glass.

    Here is what is listed for funhouse. Marco shows all the measurements for the individual pieces of trim:

    And since many of those are out of stock, here's what PBL has:

    WTF with that gap? I bought a glass from them a few years ago and it was printed all the way to the edge as expected and normal. That doesn’t look right.

    I just received this as the current CPR funhouse glass. $269.00

    Some kind of edge trim might cover it, but its a lot of unpainted edge I agree, I was a bit surprised by it.

    I have 4 different types of trim, none of them fit correctly and splay out a lot due to the thickness of the glass.

    Its disappointing to see the huge area of inpainted glass at the edges.

    I dont know it this is correct for CPR glass or I have part of a bad run?

    So, Im taking it to pinside for solutions.

    I also ordered a IJ and a TAF glass for future projects.

    I hope that there is a solution as this glass is quite expensive.

    There's definitely something wrong there! Have you contacted CPR and supplied those same photos?

    Please report back once you've heard from them.

    #9 1 year ago

    meanwhile I ordered these trims from pinball life:

    https://www.pinballlife.com/backglass-side-trim-for-williams-system-11.html

    https://www.pinballlife.com/backglass-top-trim-williamsbally-wpc-95.html

    The pictures show that there is no ridge inside to adversely affect installation like the ones I already have.

    But one never knows what they will get these days

    Following. I just ordered new glass for my Indiana Jones and Twilight Zone. Should be here next week. I also have a new trim kit as well for the Indy. I hope it fits?

    If the trim has a rib or ridge inside it wont fit.

    I have lots of trim and none of what I have fits at all.

    Marco is great as they have actual side views of the trim.

    WPC-95 trim looks good, I ordered some. as well as some system 11 trim.

    I also ordered a 1/8" metal lift channel as it had no internal ridge.

    #13 1 year ago

    I also have friction tape to help any trim that fits too loose.

    #14 1 year ago

    Keep us posted if you find something that works. I will do the same.

    #15 1 year ago

    I know it may not be easy. Can you give us a picture with glass installed with only the lift trim? Full shot.
    That is a big gap.
    I have 3 of these as well and used the system 11 pbl.

    I ordered that as well as another one.

    They will be here in a couple days.

    Ill post the result for others to see.

    My stainless trim arrived for the lift trim from Marco.
    I think Im going to use it. Its way better for supporting the heavy glass, the edge doesnt bend as much under weight.

    Still waiting for the system 11 trim from pinball life.

    #18 1 year ago

    I got the system 11 trim today.

    Its the perfect fit!

    So, its definitive.

    Get the system 11 trim.

    It has no ribs going down the inside.

    Its the perfect size.

    No hammering, no stress.

    It covers the clear edge perfectly.

    The CPR backglass is way thicker than regular 1/8" translite glass.

    This is why regular "ribbed" edge trim doesnt fit right.

    But the glass is slightly thinner than 3/16" backglass.

    So, the system 11 trim fits perfectly but not super snug, yet it stays on ok.

    I added 2" long strips of friction tape to the center and ends of the lift channel.

    Its super snug and perfect.

    The sides and top trim could also use some friction tape but its just not necessary.

    The tape slightly distorts the edge trim. However it makes it super snug.

    This does not happen to the lift channel when tape is added.

    Im leaving the tape off the sides and top trim for now unless its a problem down the road.

    The CPR glass is amazing.

    Im just surprised that they dont offer the trim for it when you order it.

    People shouldnt have to experiment, it should be definitive.

    Now it is.

    This is great. Thanks for sharing. My CPR order just got delivered to my front step today and can’t wait to see how it looks. FH and AFM in the box

    Did CPR respond to explain why they don't print all the way to the edge of the glass? Does this also mean that the backglass/translight image is reduced in size slightly, or just has the two edges trimmed when compared to the original?

    CPR Thomas, responded to my email and said that its normal and that the trim covers it, which is correct..

    The image is reduced slightly. It doesnt go all the way to the edges like the translite did,

    I bought 2 more backglasses, but havent looked at them yet to compare more or less gap.

    I think others have stated that there is a 1/4" or more clear edge that has to be covered with trim.

    There are registration marks on the clear areas.

    Can anyone else, who might have purchased a glass recently confirm this?

    Either way, the PBL system 11 trim is perfect.

    Thanks for the detailed response. It seems like a strange decision initially to use thicker glass, reduce the image size and leave a narrow strip. Especially without providing advice to customers prior to purchase of the type of trim required, or just supplying a trim set with each purchase. Most people, including myself would assume the glass would be ready to install. It's great these glasses are available, just frustrating this information isn't readily available prior to purchase.

    I have to agree with a lot of this.

    However Im actually very pleased that the backglass is thicker and a LOT more durable than standard 1/8" translite glass.

    I think they made the absolute right decision on this.

    It does pose a trim problem, as there are a ton of choices for very specialized purposes, but just use the system 11 trim.

    Its perfect.

    Can still confirm System 11 trim from PBL fit like a glove perfectly on my TZ backglass from CPR.
    Just a little pressure to install, tight fit, covered all edges of the glass.

    Amazing.

    #31 9 months ago

    Same deal on my EATPM mirrored cpr glass. I feel like they're cutting the glass too wide. Mine is so wide there are not adequate margins for any side trim. Stuck with the light bleed.

    Idea: what about blacking the edge with black electrical tape?

    I would just tape off the edge and spray it with a little krylon if its that tight.

    Amazing.

    I like to put three 2" pieces of friction tape on the lift channel.

    One in the center and one near each end.

    It makes the lift channel rock solid, although I did have to smack it on with a wooden mallet.

    ugh-i wish i found this previously-i own 3 CPR backglasses-i used the existing translite trim and really struggled to get it on but i did. White water, scared stiff and funhouse-recently i went to do some work and could not get the funhouse out of the channel-probably because the trim is stuck-eventually, after straining my back and almost losing my mind, i got it out-so i bought new trim for a standard funhouse translite-what a mistake-broke two pieces trying to install it and now its stuck in the channel again-ordered the system 11 and hopefully that works assuming i can get the glass out again-what a disaster-so weird to not have any issues with any games other than funhouse

    Ive "been there and done that".

    Its what started me on this journey.

    I have 4 CPR backglasses and couldnt get the first one mounted at all, lol. Near impossible.

    The links above take you to the correct trim.

    The pinball life system 11 lift channel and trim fits perfectly.

    #37 7 months ago

    the top and side channel sys11 trim is 100% perfect for the CPR glass

    the bottom is still a bit iffy - but worthy.

    You'll basically split your wpc trim trying to force it on. Buy a replacement wpc set and sys11 set at the same time to undo your attempt

    I do find the pinball life replacement wpc trim a bit less tight on the translite vs the original stuff I had, and unfortunately it's cut short to not overlap. I liked the longer stuff you could cut to size and notch to fit in the corners.

    Yeah, the lift channel needs the friction tape.

    After applying three 2" pieces of tape its rock solid.

    FYI this just came back from Thomas at CPR. I let him know that they should do a better job of alerting their customers. I went to the installation section and did not see anything regarding trim. Having said all that-their back glasses are really beautiful. Finally, im assuming the system 11 trims suggested in this post are the 1/8 he is referring to

    Your using the wrong trim.

    We've got all the Marco trims here, just for testing and checking. The
    1/8" trim and liftbar fit on all our panels fine.

    Thanks

    I ordered all of the trims from marco and pinball life during my investigative tests.

    CPR backglass is thicker than the regular 1/8" translite glass.

    Its in between the regular 1/8" and the 3/16" glass.

    This is why the 1/8" trim fits too tight.

    It also has to be without ribs or flanges.

    Just use the system 11 trim from pinball life and you are good to go.
