Spring Deflection to 125 lbs.

These medium duty spring loaded gate casters fit light carts, racks, and stands. Casters in this collection range from 300 to 350 lb per caster. Wheels are 3 to 5 in hard rubber and solid poly in swivel models. Spring loaded casters absorb shock and help gates and carts stay level on uneven floors. Soft rubber or TPR tread is the better pick when the floor has chips or grit. Common uses include food service, bakeries, hospitals, schools, laboratories, and material handling carts. Threaded stem, grip-ring, and expanding rubber stems for round and square tubing all appear on light-duty builds. Match plate size, bolt pattern, and overall height before you order. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy.
