D&L 4 Inch Plate Swivel Casters Wheels 1800lbs Heavy Duty Casters with Brake Polyurethane Dual Locking Casters Set of 4 (Two Hardware Kits) DL-I4-001

Highly Recommended

They are incredibly sturdy and strong. I bought them for a work table but I ended up using them for an office chair built from an suv seat. Its overkill for the job but it beats any chair currently being sold. Ill definitely buy another set when I setup my heavy duty workbench

Strong and sturdy and the wheel locks work great.

Wheels under a large miter saw table. Nice and sturdy

industrial type strength, easy rolling, wheel locks good but firm to engage

Was sceptical when ordering but when arrived quality was amazing and I used them on 3x6 welding bench made out of 3/8 plate steel cant believe how easy it rolls and locks 5 stars

Well-made set of matched wheels/casters for DIY projects. Roll well, and very sturdy, but somewhat difficult to lock and unlock.

Ive got about 500lb of Rhino blade sitting on a dolly with 3 of these casters. It rolls okay, but the casters will not change direction worth a darn. They look good, and seem fine, and might do okay with maybe 100lb per caster--but thats it. I have to kick the casters around to point the dolly in a new direction, then it rolls fine on the concrete pad.

Work really well on my welding table. Will buy again.

Smooth movement, sturdy! Great construction!
