SpiralGrip Cat Pole & Tree Upgrade System

This is a cat tree modification and upgrade system centered around spiral groove poles that make sisal wrapping fast and clean. The idea began with my stabilizer brackets and grew into this system with replacement poles and multiple types of spacers making it easy to strengthen, tune, and reconfigure commercial cat trees.Note that this is designed around poles that are ~68mm in diameter.SpiralGrip Poles:Integrated spiral groove designed specifically for 1/4″ sisal rope: insert the rope through the dedicated opening, tie a knot, and start wrappingIntended with heat set inserts and threaded rods/bolts like commercial polesA bracket-base variant is included for surface mounting, using screws for additional stability.Designed for strength via perimeter walls on the inside thanks to a hollow center cavityAre meant to be easy to size to your needsWrapping the pole Spacers:Simple cylinders and brackets with integrated spacers for small height adjustmentsLarger brackets for bigger spans where
