Overall height is 5-1\/8\" and swivel radius is 3-7\/32\".\u003c\/p\u003e\u003ch2 style=\"color:#016367;font-family:Rajdhani,Arial,sans-serif;\"\u003eTotal lock is the reason to pick this one\u003c\/h2\u003e\u003cp\u003eTotal lock means one pedal press stops the wheel from rolling and stops the rig from swiveling, at the same time. Most brakes on light and medium duty casters are side locks or top locks that only clamp the tread. The rig underneath still rotates, so a loaded rack parked on a slight grade slowly pivots and creeps, usually toward the oven door or the aisle. If your operators are loading a rack that is already parked, total lock is the spec that matters more than another 50 lb of capacity.\u003c\/p\u003e\u003ch2 style=\"color:#016367;font-family:Rajdhani,Arial,sans-serif;\"\u003eWhich plate you get\u003c\/h2\u003e\u003cp\u003e\u003cb\u003eStandard is the 2-3\/8\" x 3-5\/8\" plate\u003c\/b\u003e with a 1-3\/4\" x 2-7\/8\" to 3\" bolt hole pattern and 5\/16\" bolts. That is what ships unless you choose otherwise, and it is order code 21TL414TMA83T-01.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eThe 3-1\/8\" x 4-1\/8\" plate is an option,\u003c\/b\u003e not an upgrade and not included. Select it from the plate dropdown if your rack frame is already drilled for it. Its holes are slotted, 1-3\/4\" to 2-3\/8\" x 3\" to 3-3\/8\", and it takes 3\/8\" bolts. That configuration is order code 21TL414TMA83T-02. Both plates cost the same. Mounting hardware is not included with either one.

Four of these gives a 1,050 lb working design load, not 1,400 lb.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThe 350 lb rating is the rig, not the wheel.\u003c\/b\u003e The wheel alone is rated 700 lb. If you need more capacity at this wheel size and heat range, the limit you have to solve is the rig, so move up a series rather than changing wheel material.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCheck your duty cycle against the top of the range.\u003c\/b\u003e Glass-filled nylon ratings in this class are normally published as a peak figure for equipment that cycles in and out of heat. If your process holds near the top of the range continuously instead of cycling, call before you spec it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eRigid tread transmits shock.\u003c\/b\u003e At 85 Shore D this wheel rolls with very low effort on smooth floors and does not absorb impact. On broken concrete, floor drains, or thresholds, expect noise and shock loading through the frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eTwo total locks per cart is usually enough.\u003c\/b\u003e Two total lock and two plain swivel is the common bakery rack build, and it steers better than four locking casters.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2 style=\"color:#016367;font-family:Rajdhani,Arial,sans-serif;\"\u003eReplacing an existing caster\u003c\/h2\u003e\u003cp\u003eMeasure three things off the old caster before you order: the plate rectangle, the bolt hole centers, and the overall height from floor to the top of the plate. Overall height on this caster is 5-1\/8\". If the rack was originally built with a 5\" or 5-1\/8\" caster you can swap straight across. If you are mixing sizes on the same rack, replace all four so the deck stays level.
