worked great for me to install commercial replacement glass
I recently used the Trim-Lok EPDM Dense Rubber Window Locking Gasket to install new glass window panes into a commercial garage door, and overall, I'm quite satisfied with the results. The gasket is designed to fit 1/4” glass and 1/16” panel edge, making it ideal for my specific project.One of the challenges I faced during the installation was ensuring a smooth and secure seal between the glass and the door frame. To address this, I decided to use dish soap as a lubricant to aid the insertion of the glass into the gasket. This turned out to be an effective solution, as it made the process significantly easier and reduced the risk of damaging the glass or gasket.The installation process went smoothly, and the gasket proved to be durable and reliable. It held the glass firmly in place, ensuring a tight and secure fit. I appreciate the high-quality EPDM rubber material used in the gasket, which provided excellent protection against weather elements and potential wear and tear.Once the installation was completed, I was pleased with the final appearance. The gasket's design provided a neat and professional finish, enhancing the overall aesthetic of the garage door. The windows now allow natural light to enter the garage while maintaining a strong seal, which is essential for security and insulation.Overall, the Trim-Lok EPDM Dense Rubber Window Locking Gasket proved to be a valuable component for my window pane installation project. The use of dish soap as a lubricant was a helpful tip to ensure a smooth installation process. The end result is visually appealing, and I have confidence that the gasket will provide long-lasting performance. I would highly recommend this product to anyone looking to install or replace window panes in a commercial garage door or similar applications.

It works
Great product. It works as it should. Yes it is hard to install if you do not understand how to do it. No it does not require a professional. Just research and figure it out before you try to do it. A heat gun does help in tight radius corners.

This is a quality product.
This is a good quality rubber window gasket. It is fairly stiff and hard to work with as it should be in order to hold glass in place and stand up to weather. Again it is a bit hard to work with, thus the rating, but it should be. Just want to clarify that if you experience difficulty installing it.

Great product, get the right tools to install!
It's a great product for window replacement. But, depending on where it is on the vehicle l, it may be a two person job; do yourself a favor, install it wetted down with warm soapy water, after letting it warm up in the sun, and use window installation tools to get it seated properly. You'll save yourself lots of time and frustration if you do those steps!!!

Took awhile to find this gasket (the right gasket) that would work on 16ga steel and fit 1/4" window. I'd like to say it was easy to use, but installation if not done by a professional with the right tools is a "bitch". But it was well worth it.

Was able to get a strong and water proof sealed window!
I had to replace a window on my workboat. It was not an easy process getting the window and seal in. It was the first time I did it. Easy to use gets three stars and this is due to my installation abilities. Warmth?.... I really don’t know how this applies other than the warmth I felt after the difficult job was done .... 5 stars.
