Yakima Accessory Lock Housing - 8007220
Make just about any accessory lockable with an SKS accessory housing. Use with bike, boat or BasketCase accessories that don't accept SKS lock cores. SKS lock cores sold separately.
The Accessory Lock Housing is used to lock rack accessories to a vehicle's crossbar. It works in the place of a hex key to secure a bolt to a particular component, such as a wheeltray & SNAR or fairing & bracket.
