Light Duty Model 4A

PLATE MOUNT Swivel Caster Offering 2″ Wide Wheels for greater application diversity.

Caster Model 4A is intended for use in institutional applications of up to 1,200 Lbs on a set of four casters. These casters are a slightly heavier version of our Model 3 shown on this page.  These casters distinguish themselves by using 2″ wide wheels, offering a much larger diversity in wheel color and type to suit any application.

As with all lighter duty casters the steel swivel and rigid frames are not designed to withstand shock loads, impact or abuse. If your application involves that type of environment select from our broad selection of industrial casters starting with Model 9 rated for 900 Lbs per caster. Model 4A, Model 3 and K3 are stampings. They are designed for intermittent usage only on manually moved equipment.

In production applications where equipment is moved about frequently in less than an ideal operating environment select from one of our many industrial casters.

Mounting Plate – 2 3/8″ x 3 5/8″

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
