1" Slip-Sleeves

I was worried the black plastic might look cheap, but the matte finish blends right in with my poles. The 8 pairs are more than enough for two full shelves, and the friction fit keeps them from sliding when the units shift.

The sleeves fit snugly over the 1-inch posts and hold the shelf boards steady without any wobble. Eight pairs gave me exactly enough for both of my shelving units.

Took a chance on these since my poles are exactly 1" and they clicked on with zero wobble. The black plastic looks clean against the chrome, and eight pairs covered both of my shelving units perfectly.
