Product Description
Product Spec Sheet : 
48" x 48" Thermally Broken Equipment Access Roof Hatch
If you’re not digging the ADC-E-50TB, there’s always another option you can choose and that is the BA-F-50TB Thermally Broken Equipment Access Roof Hatch. There are several differences that both of these roof hatches have aside from the equipment and ladder access.
The ADC-F-50TB also has a thermally broken curb with integral capflashing 11 ga. aluminum with the corners fully welded. The cover liner is 18 ga. aluminum, and there’s a 3” (75mm) polyisocyanurate insulation for both the curb and cover. An EDPM gasket is installed around the cover. There’s a slam latch with inside and outside handles with padlock hasps to ensure it closes firmly. A lifting mechanism with reinforced composite tubes and compression springs. What makes the ADC-F-50TB better is that the hatch can be opened wide up to 87 degrees. A heavy-duty hold open arm keeps the door intact and it has a red vinyl grip and cover release.
If ever these specifications met your standards, don’t hesitate to contact Best Access Doors Canada and get the ADC-F-50TB!
