Depicted here are various safety rail mounting methods. A variety of ladder-rung clamp kits are available to fit round or square ladder rungs. AP clamp kits are made of the same materials as the safety rail to ensure compatibility of metals. There are provisions for mounting the safety rail, not only on ladders but also angle tower legs and wooden or metal poles. Shown are two illustrations indicating typical splice connections which make the rail continuous from the bottom to the top of the climbing ladder.
You may have an unusual mounting problem. If you do, please call so we can be of assistance.
