These plastic wall spacers maintain the required expansion gap between plank flooring and adjacent walls, even in cases where the wall has been undercut. Their distinctive V-shaped design enables one end to fit securely into the gap while the opposite end braces firmly against the plank, preventing the tipping common with traditional spacers. Each spacer has two thickness options—3/16" on one end and 1/4" on the other—to accommodate various manufacturer specifications. Sold in packs of 10 spacers. Net weight: 5 oz.
