Heavy Duty Gate Caster, Spring Loaded Gate Wheel, Swivel Caster Wheels for Wooden Gate and Fence 220LBS Capacity

Stable Construction: Combined with thickened galvanised steel brackets and a premium PP material wheel, this gate wheel with brake is able to hold up a door or fence of 220 LBS (per caster) effectively. The ball bearing in this gate wheel helps you adjust the direction of movement with ease.
Built-in Spring: The unique built-in spring design not only prevents sand and gravel from entering the spring and causing damage and scratches, but also lessens the effects of rain and sun exposure on the spring, which prolongs the lifespan of the spring.
Absorb Shock: The extension of the spring is up to 1.73 inch, which assists it in supporting the gate nicely and balancing the loading of the gate well. At the same time, it enables the wheels to move steadily on uneven ground. Please note that it could not be used on some deep pits or extremely uneven ground.
NOTE: To prevent the gate from suspension when the gate casters meet a concave ground, it would be necessary to press the spring of the gate wheels in advance during installation. So that the gate wheels would be able to support the gate while moving to a concave floor.
Package Includes: The package contains 1 x Spring-loaded gate caster wheel, 2 x 90mm*M10 bolts, 2 x M10 nuts and 2 x washers
