Designed to fit square tubing commonly found in ornamental fence designs, Square Fence Collars are a component of the gate latch assembly. Using carriage bolts and nuts to secure in place, these two-piece collars attach to the square posts to install a fully functioning, reliable gate fork. Our Square Collars have a steel composition with a galvanized finish that features corrosion-resistance for long-lasting outdoor performance. The Square Fence Collars fit post sizes ranging from 1 1/4" Sq. to 2" Sq. and require carriage bolts for installation, sold separately.
