Technical Specification


The ManSafe Freestanding Constant Force post provides assured worker safety at height where there is an occasional or temporary requirement to access flat roofs or structures.

At the heart of the system is Latchways’ unique Constant Force technology. The Constant Force post is contained within an anchor device consisting of a galvanised steel frame and galvanised steel weights bolted in a circular formation onto rubber coated base weights. In the event of a fall, the Constant Force post deploys to limit the load on the system while the weights simultaneously create a friction anchor between the unit and the roof surface.

Applicable where there is an occasional safety at height requirement.
Suitable for flat roofs (maximum 5° pitch).
Can be used on a wide range of roof surfaces including concrete, single-ply membrane, bituminous membrane, sanded and stone chipping asphalt, and steel profile.
No need to puncture the roof membrane to fix the system.
Special rotating anchor turns through 90° for maximum user flexibility.
Each anchor device protects a single user.
Conforms to BS EN 795 class E.

Specification Details

The Freestanding Constant Force post is for use as a single point anchor conforming to BS EN 795 Class E and can also be used as part of a Latchways ManSafe horizontal cable system, which has been independantly tested.

The post is used on nominally flat roofs up to a maximum pitch of 5º where it is impractible to install traditional Constant Force posts or rigid anchor posts to the roof or supporting structure. The post has been tested and approved for use on concrete, single ply membrane, bitumen membrane, asphalt-sanded, asphalt-stone chipped and steel roof profiles. If the roofing profile which you have selected falls outside the current range, please contact Latchways technical department on 44 (0) 1380 732700 for further advice.

The interlocking segmets are arranged in a circular form, ensuring that the post is omni directional. Each segment has an integral carry handle and is a maximum weight of 25 kg. Ensure no part of the anchor device is less than 2.5 m from any roof edge including skylights, hatches etc. Where appropriate, remove any loose chippings prior to assembling the post. When connecting to the post or system, always use a full body harness and energy absorbing lanyard to appropriate national standards.

The post must never be used during periods of adverse weather conditions (i.e. frost, snow or freezing conditions) or if the roof surface is contaminated by algae, grease, oil or any other type of lubricant.
Testing / Maintenance

Constant Force posts should be tested annually by an authorised installer or agent. Contact Latchways Sales Department for details of certified installers.
