Stage glass, this has nothing to do with the theater

Stage glass or glass platen is the most frequently broken part of your overhead projector. I would like to share some of the stories that I have had the pleasure of hearing when my clients call to replace this part.

Replacing the overhead projector stage glass is probably one of the easiest repair jobs any overhead projector end user can do. What is a stage glass? It is the glass stage where you place your transparencies when projectors are projected. The stage glass or glass stage, as some call it, is one of the most frequently replaced parts in an overhead projector today.

Now, unfortunately, it’s easy to get confused as to which replacement stage glass your overhead projector may need, as there is no standard size or shape for stage glass from any manufacturer, be it 3M, Dalite, Buhl, Eiki, Bell & Howell. , Dukane or Elmo stage glasses come in many different sizes and configurations.

Some Stage Glass may have beveled edges running the length of the glass on one or two sides. Some Stage Glass may have cut corners, sometimes referred to as four-corner or two-corner trimmed corners.

Some Stage Glass is called toughened glass. Tempered glass is specially heat-treated glass that makes it much more durable than the typical annealed glass used in most overhead projectors.

Some Stage Glass is attached with clips, while other Stage Glass is attached with double-sided tape. As you can see, there is a wide range of variables when it comes to overhead projector stage glass.

If you have a stage glass attached with double-sided tape, you must remove the old tape and reattach it before installing the new glass. It is not recommended to use the same double sided tape for your new Stage Glass.

In some cases, the manufacturer does not allow you to purchase the Stage Glass if it requires double-sided tape to reinstall it. In those cases, you will be asked to purchase a new top cover assembly with the Stage Glass already installed. In some cases, once you have purchased the new top cover, the Stage Glass will be fastened with clips instead of the double-sided tape, allowing any future glass replacement to simply require the purchase of just the Stage Glass.

So how do you break all these Stage Glass? Well, here are some of the most common stories we hear:

I used my overhead projector as: a stool, a ladder, a desk to staple documents,

a workbench or chair.

Some people prefer to hit them or drag them from cars, while others just get completely stressed out and throw them away.

One of my favorite stories to date is one that I heard recently. Apparently the customer was very upset that his stage glass had just been smashed. After I had finished asking for all the relevant information, they felt the need to relieve some of their stress by explaining how the stage glass was broken. It seemed like a good idea at the time that they take a very large book as their weapon of choice against the fly that had been torturing them all day. The book was thrown towards the fly, it seemed to be right on target as it crashed against the glass. Unfortunately for them, the fly anticipated their strategy and evacuated just in time to get out of the way of the book only to live another day. Hopefully another overhead projector stage glass doesn’t experience the same demise.
