Constant Force for Standing Seam roofing

Constant Force for Standing Seam roofing

MSA's Latchways engineered lifeline system incorporating the Constant Force post is applicable to all the major forms of standing-seam roofs. It operates horizontally and along inclines and can be designed to accommodate up to three simultaneous users.

The Constant Force posts are top fixed to the roof sheet with four split clamps by a process that does not compromise the integrity of the roof. Equally important, in the event of a fall, all the loads generated on the system are absorbed by the Constant Force posts and therefore no damage is impacted on the roof sheets to which they are attached.

To enhance the overall aesthetic appearance, the Constant Force posts can be supplied colour matched to the roofing sheets.

Testing / Maintenance

  • System testing must be conducted annually to ensure that system certification is maintained. Key system checks such as integrity of the Constant Force post, swage tests and torque checks are part of this process. System testing and maintenance should only be undertaken by trained and certified installers.
  • Contact Latchways Sales Department for details of certified installers.

User Instructions

  • Only attach to the system by means of a retractable fall arrest lanyard and full body harness conforming to the appropriate safety standards.
  • Always check pre-tension before use.
  • No more than the maximum number of personnel as defined in the system user instructions should attach to the system.
  • Further details are available in the user instructions.


MSA Latchways fall protection system incorporating the Constant Force post can be deployed across virtually all the major standing-seam roof types.
