This combination provides wear resistance, corrosion resistance, and rust resistance for longlasting durability in outdoor environments. Strong load capacity with noticeable lift Supports up to 500 lbs to help prevent gate sagging and reduce hinge stress. The wheel is positioned 83/4 inches from the bottom to the center of the attached pipe mast, delivering up to 83/4 inches of lift to the gate. Clear compatibility and sizing Fits 15/8 to 2 inch round fence pipes. Wheel diameter is 6 inches and overall length is 10 inches. Inspect your gate frame for compatibility before . Easy and secure installation Includes adjustable steel Ubolts for straightforward mounting at the bottom pipe of the gate. Adjust to the desired height and tighten the washers and nuts securely so the caster stays fixed and does not slip against the pipe. Practical use scenarios 1) Driveways and entry gates that sag over time: install at the bottom to lift and stabilize the gate, reducing hinge wear and making opening smoother. 2) Outdoor fences and barn gates on uneven terrain: large 6inch wheels improve movement over gravel, dirt, and grass while resisting outdoor elements. 3) Gates exposed to weather or salt exposure: blackcoated and hotdip plated finishes provide enhanced resistance to corrosion and rust for longer service life.
