Need to abseil off a flat roof with no fixed anchors? Does the roof edge have an upstand, parapet wall, balustrades or railings? Checkout ISC's redesigned deadweight anchors. They're portable, easy to set-up, ideal for rope access work and can now be used with standard Olympic weights.

Why use a deadweight anchoring system?

Once securely stationed on a load-bearing flat roof (less than 5 degree slope), a deadweight anchoring system can be used to suspend you up and over the roof edge barrier in order complete your tasks.

New design compatible with standard Olympic plates

ISC has recently redesigned both the trolley and a-frame deadweight anchors to be compatible with standard 25kg Olympic weight plates. This means that you can purchase your chosen anchor with weight plates (for ease and convenience). Or you can purchase just the anchor and use your own Olympic weight plates (making it more affordable). If you choose to buy weight-less, be sure to check the tech specs for the number of Olympic weight plates required for your chosen anchor (they vary).

Which deadweight anchor is right for me?

Deadweight anchors can only be used on a flat roof. Otherwise it depends on your roof edge barrier and space available.
