Anti chafing car for Schaefer 1.25" T-track

A car that fits on Schaefer 1.25" T-tracks. This car is to prevent chafing for mooring lines for boats with this track on the toe rail. The car is free sliding so will align itself with mooring lines automatically.

Also, the car is in two parts, allowing it to be put on the rail in any position without the need to slide it on from the end of the track. The two parts lock but forces from the mooring line can defeat the lock so there is a 1mm hole for a locking pin. I use 1mm aluminum rod.
