Available with built-on handrail for added safety. Surespans Sureguard System provides a permanent 3 sided built on handrail with gate for added safety for the roof hatch. Polyester powder coating available.

Sureclip

SRH Roof Hatches can be manufactured to include a safety clip which enables the safety grid to be raised and lowered with ease. The clip allows the safety grid to open with the roof hatch making access through easier. Once through the hatch, release the clip to free the safety grid and lower to protect from falling.

In this instance when exiting the roof hatch and closing the safety grid, there needs to be a means of manually closing the lid. The handle and cord is connected to the lid of the hatch and easily fits between the safety grid to enable the lid to be closed with ease.
