The Fence-Loc Heavy Duty Single Gate Latches from Cargo Protectors provide a high-security solution for single swing chain link gates in commercial and industrial environments. Available in two sizes, these latches are designed to fit both standard 2-3/8″ O.D. posts (FL400) and larger 2-7/8″ O.D. posts (FL401), making it easy to select the correct fit for your gate system while maintaining consistent performance across both options.
Each latch features a captured locking design that secures the gate to the post while protecting the padlock from bolt cutter access. This design provides a more secure alternative to traditional fork or gravity latches by reducing exposure to tampering and improving overall gate security. With an adjustable 2″–6″ range and front-access operation, Fence-Loc latches are ideal for industrial yards, storage facilities, and commercial access points where reliability and durability are essential.

Buying Guide: Fence-Loc vs Strong Arm Latches
Fence-Loc latches are designed for applications where security and durability are priorities. The captured locking design and protected padlock area provide a more secure solution compared to traditional latch styles.
A strong arm walk gate latch is a durable and widely used option for many chain link gates and offers simple, reliable operation. However, because the locking point is more exposed, it is easier to access. Fence-Loc latches provide an added level of security while maintaining ease of use, making them a strong choice for commercial and industrial installations.
