Ratchet Strap Drill Winder Spool

A spool that winds loose ratchet straps and tie-downs into a tidy coil instead of a tangled ball: thread the strap tail through the two 3.6 mm slots in the drum and spin it. The 88 mm flanges and 54 mm clear drum take a 2 in (50 mm) strap, the Ø16 mm spindle has a 6.7 mm across-flats socket for a 1/4 in hex bit so a cordless drill does the winding, and an 8.3 mm cross hole takes an 8 mm rod or screwdriver shank as a hand crank.

Flagged: lifting or tensioned load. Not for safety-critical use without independent engineering review.
