Product Details

Security Boss designed the pin lock that is used on the Security Boss pet door to last indefinitely. Under rare occasions this item has had to be replaced. When locking and unlocking the locking pin you should ALWAYS turn it clockwise. The lock quarter turns in the clockwise direction, by turning it counter-clockwise you run the risk of un-threading the nut on the backside and losing the lock. (This being one of the rare occasions you would need to purchase an additional lock).
