Supports heavy doors up to 330 pounds per wheel, making this gate caster suitable for large wooden or steel gates that are difficult to move or strain hinges. Spring‑loaded design absorbs shock and reduces stress on gate frames and hinges. The spring also helps limit debris entry into the mechanism for more reliable, longlasting performance. Heavy‑duty rubber wheels and a rotating plate provide smooth 360° rolling so gates can be moved in any direction with minimal effort. Reduced friction means easier opening and less wear on gate hardware. Universal mounting plate and included bolts make installation straightforward on a variety of gate materials and styles. The plate fits common mounting patterns so you can attach the caster to wood, steel, or composite frames without special adapters. Practical benefits: reduces hinge maintenance, prevents sagging by supporting gate weight, and improves day‑to‑day gate usability for one‑person operation. Compatibility and performance: rated load capacity 330 lb per wheel; heavy‑duty rubber wheel material for quiet operation; spring mechanism for shock absorption; rotating plate for full swivel mobility. No additional parts required for typical installations beyond the supplied bolts. Use scenarios Residential farm gate: add one or two casters to large wooden or steel field gates to prevent sagging and make daily opening and closing easier. Garage or workshop sliding gate: support the gate weight at the outer edge to reduce strain on the track and rollers, improving smoothness and longevity. Commercial property or storage yard: retrofit heavy access gates to allow single‑person operation and reduce wear on hinges and frame.
