Part # Q523038HDPTLB
3" x 1-1/4" Heavy Duty Plastic Wheel Swivel Brake Caster, 3/8"-16 x 1-1/2" Threaded Stem - Part # Q523038HDPTLB
Polyolefin is a durable type of plastic that yields a high shock load while offering excellent impact & abrasion resistance. These wheels are lightweight yet hold high weight capacities. Unlike softer tread wheels, these wheels resist flat spotting over time. They are also impervious to water, washable, & highly resistant to chemicals, cleaning solutions, solvents, oils, & grease. These features, combined with their economical price point, make polyolefin wheel casters a popular choice.
We recommend polyolefin for a wide range of applications. However, its hard, non-marking tread can trap dirt & debris, which may scratch delicate floor surfaces, making it a less suitable choice where floor protection is a priority. If this is a concern, we recommend our thermoplastic rubber wheel options, as they offer non-marking floor protection while maintaining the same resistance to environmental factors.
This caster features an all-steel top lock brake that performs well in a wide range of applications, including those involving heat. The side-mounted brake pedal provides a more compact design than face contact & total lock brakes. The compact design minimizes the swivel radius, allowing the caster to spin freely 360 degrees with minimal obstruction. Casters with front-mounted brake pedals require more clearance to achieve full rotation.
* To tighten the caster, locate the 3/4" nut on the underside of the stem & tighten with a 3/4" wrench. Refer to the product images for reference
NSF Certified: Tested & approved for use in commercial kitchens & food processing environments where cleanliness & contamination control are essential.
RoHS Certified: This caster is environmentally responsible & free of restricted hazardous chemicals.
