The Colson Elastique E422RB is a 4" x 1-1/4" blue elastic rubber swivel caster rated 330 lb capacity, mounted on a 3-1/8" x 4-1/8" top plate. The non-marking elastic rubber wheel absorbs shock, sheds debris, runs quiet on hardwood and concrete, and protects sensitive equipment in road cases, studio carts, touring rigs, and AV production. Roller bearing wheel for sustained capacity. Made by Colson Group USA. In stock at CasterHQ Mansfield, TX with same-day shipping on quantities of 1-100 placed before 2:00 PM Central.
I spec the Elastique series whenever floor protection, quiet roll, and shock absorption matter as much as capacity. The blue elastic rubber compound has the impact-damping characteristic of pneumatic without the air-loss failure mode. Pair with the matching rigid version on the trailing axle for true four-position cart kinematics.

Quick Answer: The Colson Elastique E422RB is a 4" x 1-1/4" blue elastic rubber swivel caster engineered for case goods, road cases, music tour equipment, film and photo studios, broadcast carts, theater stage equipment, museum art handling, and AV rental fleets. The non-marking elastic rubber wheel absorbs shock, sheds debris, runs quiet, and protects sensitive equipment and the floors it rolls on.
Constructed with a precision roller bearing, zinc-plated steel rig, and elastic rubber wheel compound. Built to handle the punishment of repeated load-in/load-out cycles. The 4" wheel diameter rolls cleanly over expansion joints, cable runs, and uneven surfaces. The 3-1/8" x 4-1/8" top plate provides industry-standard mounting compatibility with road cases, racks, and dolly frames.
Hard polyurethane marks hardwood and transmits shock to fragile electronics; pneumatic wheels go flat under stage and transit conditions. This elastic rubber compound delivers floor protection AND impact absorption, with no air loss to worry about mid-tour. Rated 330 lb per caster, the E422RB sustains capacity over thousands of cycles without raceway degradation.
On 4" Elastique casters, expect substantially longer service life vs comparable phenolic or hard polyurethane on stage and studio floors. The compound is what makes it: it absorbs shock at the wheel instead of transmitting it through the bearing, the case, and into the equipment inside.
At home wherever quiet operation, floor protection, and shock absorption matter as much as load rating: touring sound and lighting rigs, recording studio rolling racks, broadcast carts, theater prop carts, museum and gallery art-handling carts, library and archive carts, hospital quiet-roll equipment, AV rental fleets, and trade show booth setups. Pair with the matching rigid version on the trailing axle for true four-position cart kinematics.

Choose the Colson Elastique E422RB when you need a non-marking, shock-absorbing, quiet-roll caster that survives high-cycle professional use. Made by Colson Group USA. In stock at CasterHQ Mansfield, TX with same-day shipping on quantities of 1-100 placed before 2:00 PM Central.
This Colson Elastique E422RB 4" x 1-1/4" Blue Rubber Swivel Caster — 330 lb is rated to 330 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Blue Elastic Rubber wheel with a 1-1/4" tread width. Rubber absorbs shock and protects floors, and runs quietly, which suits noise-sensitive and light-to-medium duty use.
This caster uses a top-plate mount with a 3-1/8" x 4-1/8" plate and a 2-3/8" x 3-1/8" bolt pattern. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Blue Elastic Rubber wheel performs best on rough, uneven, or outdoor surfaces such as asphalt, gravel, and cracked concrete. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 5". Account for it when checking equipment clearance, dock height, and ergonomic working height.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
