MotoZipp™ Extra Heavy Duty 250-pound

These UV-resistant cable ties are the heaviest and strongest on the market, with a working load of 250 LB.  The locking head means they stay in place, but because the locking tab is so large you can release the lock with a flat screwdriver or knife blade and re-use them. Operating temperature of -40F to 185F so you can use them outdoors with confidence.  Black. Width 0.50″.
