シェルフユニット＆ユーティリティカート用4インチキャスター

The locking mechanism clicks in place with a satisfying snap, and these polyurethane wheels roll so smoothly over my garage's uneven floor that I barely feel the bumps. They fit my 1-inch shelving poles perfectly, and after a month of daily use, they've held up without any wobble.

Swapped out the old casters on my utility cart and these swivel smoothly even loaded down with paint cans. The polyurethane wheels grip better than I expected on my garage floor, and the two locks are handy for keeping the shelving from rolling when I'm reaching up high.

The polyurethane wheels roll so smoothly over our garage floor that I actually forgot they were on the cart until I needed to lock one. The two locking casters are a godsend on our sloped driveway, holding the shelf steady while I load heavy boxes.
