PRODUCT CODE: E429RB
The Colson Elastique E429RB is a 4" x 1-1/4" blue elastic rubber rigid caster rated 330 lb capacity, mounted on a 3-3/4" x 4" 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 swivel version on the steered axle for true four-position cart kinematics.

Quick Answer: The Colson Elastique E429RB is a 4" x 1-1/4" blue elastic rubber rigid 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 3-3/4" x 4" 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 E429RB 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 swivel version on the steered axle for true four-position cart kinematics.
