Product Spec Sheet : 
30" x 54" Thermally Broken Ship Stair Access Roof Hatch
Using a 90 degree access ladder can be tedious to walk on at times. Instead of a usual 90 degree access door, you can use the ship stairs. And for this type of stair, it needs a specific access door. You now have the choice to install the ADC-NB-50TB Thermally Broken Ship Stair Access Roof Hatch.
It is a ship stair access roof hatch that has a thermally broken curb and cover. The curb has an integral capflashing 11 ga. Aluminum with corners fully welded. The cover is also an 11 ga. Aluminum. To ensure the roof hatch closes properly, there is a slam latch with inside and outside handles with padlock hasps. You’ll be happy to know that the ADC-NB-50TB has a lifting mechanism with reinforced composite tubes and compression springs, making sure the hatch smoothly opens and closes.
You can get it as an aluminum mill finish and the hardware is corrosion resistant. So if you’re ever planning to use ship stairs to the roof, the ADC-NB-50TB can get the job done!
