Gundlach Long Aluminum Straight Edges (5/set) — The Straightest, Strongest Edges for Flat Floors
A straight edge that isn't truly straight — or that bows the moment you lean on it — quietly ruins a flat floor. This is Gundlach's straightest and strongest set: heavy rectangular clear-anodized aluminum that resists flex, and unlike wood or steel it can't rust, rot, or warp. Both ends of each edge are plugged with a plastic insert so mortar can't pack into the tube and weigh the tool down.
Five nesting lengths — 6', 4'10", 4', 3', and 2' — cover everything from a small area to a long screed pull, and the spring-loaded two-piece carrier keeps them tensioned so they don't slide around in transport, with a U-shaped bottom for easy reloading. To strike a mortar bed with an L-angle profile, the L-Shaped Mortar Screeds are the companion set.

Pro tip: Check each edge against a known-flat reference now and then, and store them in the carrier rather than loose in the truck — that's what keeps them dead-straight over time.
