Master Lock 8109D Compact Cable Lock, Silver, 5-Foot X 5/16-inch
The Master Lock No. 8109D Keyed Cable Lock is 5ft (1.5m) long and features 5/16in (8mm) diameter braided steel for maximum strength and flexibility. The protective vinyl coating protects against scratches. The integrated pin tumbler keyed locking mechanism provides superior pick resistance. The Limited Lifetime Warranty provides peace of mind from a brand you can trust.
*Recommendation: An 8ft board or shorter sitting in a 5.5ft truck bed could use a 5ft cable when clocked to a rail hook. However, a 10ft board would likely need an 8ft cable when secured to the same hook.
