Stop your Kunai's attachment rope, cam buckle strap, etc. from sliding off the platform's hooks while setting it up on the tree. The stock hooks on the Timber Ninja Kunai Hybrid Saddle Platform are great for quick setup, but without something to secure the line, the amsteel rope can easily slip free when getting it set up on the tree. These 3D-printed Rope Lockers bolt right on and keep everything locked down, no more struggling in the tree or losing your composure while getting set up.
How it works
Mount each locker to the platform using the existing hole near the rope attachment hooks (one per side).
Secure with the included 10-24 bolt and locknut—simple install, no drilling or mods needed.
The locker pivots over the open portion of the hook to close it off, trapping the rope or strap so it can't slide out accidentally.
When you're ready to detach, just pivot the locker open—the hook is fully accessible again in seconds.
