Protect your fine woodwork by installing your gate with our premium clamps, no need for screws or holes. Crafted from solid wood, these clamps come in a variety of sizes to fit square posts, ensuring a secure and reliable mounting for your gate. The Large Square Clamp fits square posts with a width up to 5″ and depth of 0″ to 4.5″. If your square post width is 3.5″ or smaller, consider our Square Clamp or Small Square Clamp. Note: Clamps are sold separately from gates. Two clamps are needed per side when attaching to a banister or post. The provided dimensions are based on the included 1/4″-20 bolts. For custom widths, shorter or longer 1/4″-20 bolts can be easily sourced at your local hardware store. • Made in the USA: Cardinal Gates has been in business since 1993 and our operations are based outside of Atlanta GA.
