The Cardinal Gates Square & Round Clamp Kit offers a secure, damage-free way to mount safety gates to both square and round posts—perfect for homes where preserving woodwork and finishes is important. Crafted from solid wood, these clamps allow you to attach baby or pet gates without screws, drilling, or permanent alterations. Round Clamp: Designed to fit round posts from 2.125 inches to 3.75 inches in diameter. Square Clamp: Designed to fit square posts up to 3.5 inches wide. Each clamp delivers a sturdy, reliable hold, ensuring your gate stays firmly in place. For proper installation, two clamps are required on each side of the gate.
