Simply fused on: Anchorage point for bitumen and plastic roof membranes

Our ABS-Lock OnTop anchorage device offers you a unique anchor solution for bitumen sheeting and fabric-reinforced plastic membranes. This single anchorage point is simply fused onto the roof membrane - without the need to open it up or penetrate it.

The system crossbars are completely covered over using the same material as your roof membrane. The patches are simply fused onto the roof membrane surface. Once professionally installed, our ABS-Lock OnTop offers a reliable anchorage option for securing up to 3 individuals at any one time.

This fall protection system is based on an aluminium cross-shaped anchor with a central anchorage eyelet attached to the top of a stainless steel support (Ø 16 mm) designed to buckle under stress. Our ABS-Lock OnTop can be used on flat roofs with a pitch of up to 10°.

We offer a specially-developed ABS-Lock OnTop Control system for roof membrane testing purposes. This can also be used for the prescribed annual inspections. This solution also ensures that your roof surface has the required load-bearing capacity.
