Attwood’s Trailer coupler locking pin is structurally strong to prevent the coupler from accidentally disengaging. This product is not only limited to trailer use. It is also beneficial for gardening, farming, table saw, lawn, truck, boat, trailer, or other locking applications. The product’s wire lock pins are attached to the wire loop through the top and secured over the post at the opposite end. A wire loop at the end of the bent wire slides over for straightforward securing and removal. The trailer coupler lock pin is perfect as a replacement for loose parts and locks into position with quick-release applications.
