4 Inch Heavy Duty Spring Loaded Gate Casters with Brake, 2 Pack 220lbs max capacity. Adjustable spring design absorbs shock on uneven ground. Smooth rolling for heavy wood & metal gates

EASY TO MOVE: The gate casters are fitted beneath the door, making it simpler to move the door. You can achieve the opening and closing of the door with a simple push and pull motion, which greatly boosts work efficiency and convenience.
STABLE CONSTRUCTION: Combining thickened galvanised steel brackets with premium TPR material wheels, this gate wheel with brake effectively supports a door or fence weighing up to 220 LBS (per caster). The ball bearing in this gate wheel assists you in adjusting the direction of movement with ease.
ABSORB SHOCK: The spring extends up to 1.73 inches, helping it support the gate nicely and balance the gate's load well. At the same time, it enables the wheels to move steadily on uneven ground. Please note that it may not be suitable for use on some deep pits or extremely uneven surfaces.
NOTE: To prevent the gate from sagging when the gate casters encounter concave ground, it is necessary to compress the spring of the gate wheels in advance during installation. This ensures the gate wheels can support the gate while moving onto a concave floor.
EASY INSTALLATION: These gate wheels are designed for straightforward installation, with detailed installation guides, allowing users to complete the setup quickly and without hassle. We will respond at the earliest opportunity
