Description
Rigid corners set the track a cart follows. If they do not roll straight, the operator spends the whole trip correcting, and nothing further up the cart fixes it for them.
Part number 58KT60LL6719YY is a 6″ x 3″ rigid caster on Kineti-Glide Trio wheels, rated 2,150 lb. Three wheels across the 3″ tread width give it a wide, stable stance, and that stance resists the small side loads that knock a cart off line. Less drift means less constant correction at the handle.
The three-wheel arrangement also splits the 2,150 lb across three contact patches instead of one. Lower pressure per patch means less tread deflection under load, and less deflection means less of the operator’s push is absorbed by flexing polyurethane rather than moving the cart.
The rig uses 3/8″ double-welded steel legs on a 1/2″ thick top plate, with a 3/4″ axle and a grease fitting. Wheels are polyurethane tread on precision ball bearings. Slotted bolt pattern for 1/2″ hardware. Zinc plated.

Choosing across the Kineti-Glide line
Six decisions separate the models. The specifications above tell you where this one lands on each; here is what the choice actually costs you or buys you.
- ◻Duo or Trio Duo splits the tread across two wheels, Trio across three. Trio carries more and spreads pressure further for the same wheel diameter. Go Trio when the load is at the top of the Duo range or the floor is unforgiving.
- ↻Rigid or kingpinless swivel Rigid holds a line; kingpinless swivels steer. Kingpinless is the only swivel in this line — there’s no kingpin version to fail. Two of each tracks straight and turns at one end. Four swivels turn anywhere but wander on long runs.
- ▢Integrated toe guard or top hats Where offered, the guard is cast into the yoke rather than bolted on, and the two versions of a rig carry identical ratings. Take the guard anywhere people walk beside a moving cart. It costs no capacity.
- ➲Standard or extended swivel lead Swivel lead is the offset between the swivel centreline and the axle. A longer lead lets the load swing the wheel into line instead of the operator. Extend it on carts that turn constantly. Straight-line runs won’t notice.
- ⚙Greaseable or maintenance-free Greaseable rigs have fittings at the axle and raceway. Maintenance-free rigs have neither and no interval to track. Go maintenance-free if caster PM is realistically never getting done.
- ◫Mounting footprint Three top plate sizes across the line, all with slotted bolt patterns. A bigger plate spreads mounting load across more of the frame. Size up on heavy decks, rough floors, or a frame with a history of plates working loose.
The gap between the wheels
Splitting the tread across two or three wheels leaves gaps that a single wide wheel doesn’t have — and on a plant floor, a gap is somewhere for debris to go. Kineti-Glide wheels are set close together so there is far less room for anything to lodge in between them.
It matters because debris in that gap doesn’t just sit there. It packs against the axle, holds one wheel while the other keeps turning, and scores the tread from the inside where nobody sees it until the caster is already dragging.
The tighter the gap, the less of that there is to clean out — and the less often anyone has to lie on a workshop floor with a screwdriver to do it.
1/4″
Between every wheel
The same on Duo and Trio, every diameter, every rig in the
line. Wide enough that the wheels still turn independently
through a corner, tight enough that there is very little
room for anything else.
How much force should it take to push a cart?
There is no OSHA limit on push force, so the question is not what is allowed but what a person can do all day without wearing out. These are the published ergonomic design goals, and what they mean for the caster you put under the cart.
Almost no caster site will answer this, so here is the answer and where it comes from. There is no OSHA limit on push or pull force — it falls under the General Duty Clause.
What most industrial ergonomics programs use instead is the Liberty Mutual Manual Materials Handling Tables, the research Stover Snook and Vincent Ciriello ran at the Liberty Mutual Research Institute for Safety. They are free to use online, and the design goals below come straight out of them.
Where these numbers come from
The Liberty Mutual pushing tables, read at the design goal of 75% acceptable for women, a middle push height (hands around 36″), a 7 ft push, once per shift.
They are not a fixed limit. The tables move with push height, distance and how often the push repeats — a cart pushed every minute for 60 ft has a far lower acceptable force than one pushed once a shift for 7 ft.
Look your own case up in the Liberty Mutual tables rather than taking ours.
| Design goal | Force | Reading it |
|---|---|---|
| Initial push | ~60 lb | Breaking the cart out of a stop. This is the number operators complain about. |
| Sustained push | ~42 lb | Keeping it rolling once it’s moving. Always lower than the initial force. |
| Adjustment for men | ×1.5 | The figures above are the women’s goal. Liberty Mutual’s own multiplier for men is about 1.5, ranging 1 to 2. |
| Pushing vs pulling | Push | Pulling loads the lower back harder than pushing the same cart. Spec the cart so people can push it. |
What we won’t do is promise you a number. Push force depends on wheel diameter, tread, bearings, floor condition and how the load sits on the cart. A caster is one input of five. Anyone quoting you a force without knowing your floor, your load and your cart is guessing — tell us those three on the phone at (888) 276-3386 and we’ll tell you straight whether these help, including when the answer is no.
Getting the spec right before you order
Three measurements and one piece of arithmetic. Take these off the equipment you’re fitting, then check them against the specifications table above.
- Work out the load per caster Divide the total loaded weight by 3, not 4. On a real floor one caster is always slightly off the ground, so three are carrying the load. Add 20% on top — more if it crosses dock plates or expansion joints, or gets towed.
- Measure the top plate and bolt pattern Plate length × width, then bolt hole spacing centre to centre both ways. Replacing existing casters? Pull one off and measure it rather than the frame. Every plate in this line is slotted, which gives some range.
- Check the overall height Floor to the top of the mounting plate. This sets deck height, and on a cart that loads at a fixed station an inch matters. Swivel and rigid casters on the same cart must match.
Replacing casters on existing equipment? Send us a photo of the old caster with a tape measure across the top plate. That’s usually all we need to match it — get in touch.

Not answered here?
Tell us what the caster has to carry, what the floor is like and what it is mounting to. We will tell you which one to buy — or that none of them fit.
Do two or three wheels really push easier than one?
Yes — but not for the reason it usually gets sold on. It isn’t load sharing. Rolling resistance rises and falls with the load on a wheel, so two wheels each carrying half the weight come out roughly where one wheel carrying all of it does. Anyone who works that out on paper will find the same thing.
What actually changes is scrub. A cart almost never travels a perfectly straight line — it corners, it gets nudged back on course every few feet, and a swivel has to break away every time direction changes. A single wide tread has to drag sideways across the floor through all of it, because its inner and outer edges are trying to cover different distances at the same time. Two or three narrow wheels each turn at their own speed instead, so most of that dragging never happens. The effort it would have cost stays out of the push handle.
Wheel diameter still matters, and it matters most in a straight line: an 8″ wheel starts and rolls easier than a 6″ of the same build, so if you have the overall height to spare, take it. The two aren’t alternatives — they fix different halves of the same problem, which is why the line runs both.
Will these fit the carts I already have?
Check the top plate size, the bolt hole spacing and the overall height against the specifications above. If the plate and bolt pattern match and the height is the same, it’s a direct swap.
If the height is different, change all the casters on that piece of equipment at once — mixing heights puts the load on whichever corners happen to be tallest.
Do you carry replacement wheels and parts?
Yes. Wheels, bearings, axle kits and brake components are available for the Kineti-Glide line, and we assemble in house — so if you need a rig from one model with the wheels from another, ask.
