Pebble Grain FRP Aluminum Hybrid Door

The SL-17 FRP Door, installed in an aluminum or fiberglass door frame, is our most popular product. This comes as no surprise because the SL-17 solves door maintenance and standard door replacement problems just as it was designed to do in 1983 for educational institutions!

The Original School Door

Students are rough on doors. They are full of energy, in a hurry and most times have their hands full of books, sporting equipment, or their phones. When a student walks up to an entrance, they know that one hard yank on the pull will throw the door wide open so they can walk through without touching the door again. But worse yet, when they leave the school add speed to the scenario! School doors get hard forearm slams, swinging gym bags or book bags, and sometimes feet kicking the exit devices. What power! What force! You need a door that takes such punishment. The SL-17 has done that since 1983!

Solving Your Biggest Headache

If you have not installed this door in your building, you should. In fact, your first installation should be in the entrance system that experiences a high level of abuse. Many educational facility managers, when asked the right questions, know where they should try the SL-17 first. Where is your biggest door headache? Is this the door that needs weekly hardware adjustments? What about the door you are constantly repainting because of dirt and graffiti? Or, is it the door that always looks like its 20 years old or plagued with rust? Yes – THAT entrance.

The SL-17 FRP Door is guaranteed to last, and the hardware we installed to stay on the door, for ten years! Just imagine the long life on the SL-17 FRP Entrance on all your hallways! Why is the SL-17 FRP Door such an over performer? The easy answer is: due to design, modern materials, craftsmanship, and pride.
