Quick-Release Track-Stop (QRTS) .

Never lose another track top overboard or need plyers.
Our light weight QuickRelease handles only require a few pounds of hand pressure to provide over a hundred pounds of track locking pressure. 
We use aluminum rods that come in two lengths, 2", 4" and we have an 8" flexible extension kit.  They will fit all track channel profiles.

The most common uses for QuickRelease TrackStop:

1.  Sailors who wants the simplest solution to keep the sail from falling out of the sail-feed slot. 
2.  Use it under a sliding goose-neck to limit boom drop during reefing.
3.  Create more head room or a taller boom tent by locking the boom higher up the mast.
