This listing is for a RARE (DIFFICULT TO FIND) SET OF 4 SAFETY PULL CLIP & SWIVEL LOCK BRAKE 6" POLYURETHANE HEAVY DUTY WHEELS as can be seen in the pictures. Buyer will receive Four (4) of these wheels in the same exact condition as seen in the pictures.
These 6" inches Diameter Heavy Duty Caster Include Built-In Rare Swivel Lock Clips as a Safety Option Device as can be seen in the pictures.
These Safety Lock Clips are considered a safety option, as a cart moved with two locked casters (rigid) and two swivels casters is much easier to handle than a cart that has four swivels. It takes a lot of force to keep a cart with 4 swivel casters on track and is more prone to operator injury when moving a loaded cart.
When you lock a heavy-duty swivel caster, you convert it into a rigid caster. The purpose of locking a heavy-duty caster wheel into a fixed position on a material handling cart is so you can transport and steer the load over long distances. Once you are near the exact destination, the caster is unlocked so that the cart can be moved in any direction to position it. The locking caster provides flexibility for ease of movement in a tight area and ease of transportation when traveling a longer distance.
How this Safety Clip Swivel Lock Heavy Duty Casters work: The Safety Swivel Lock Clip is used when full mobility of a unit is needed. The swivel lock plunger engages a detent and locks the caster for straight or side line movement. When side thrust is applied, the swivel unlocks, providing maximum maneuverability of the unit. This swivel lock is NOT RECOMMENDED for towed applications.
