Official StoreCorner Clamp 4 Pack — 5.5" / 140mm Right Angle Clamp

Four clamps, one pack, no flex

A corner clamp holds 90-degree angles while glue sets — eliminating the frustration of frames racking or joints creeping. You get four clamps in one pack, so you can clamp four corners at once, clamp two projects, or keep spares on your bench.

The locking screw is the difference. Turn it and the angle holds. Leave it overnight and it holds the same angle in the morning.

Made to fit small projects

At 5.5 inches (140mm), these are sized for picture frames, drawers, small cabinets and boxes — the scale where precision matters and fingers are in the way. Maximum clamping thickness is 3.5 inches (90mm), which covers plywood, solid wood and most framing.

Aluminum alloy with red anodized finish — it resists rust and corrosion, and won't mark or stain wood during glue-up.

Details that protect your work

Chamfered edges on the clamp body won't bite into wood grain or nick delicate finishes. The CNC-machining is why the angle stays true — not rounded or worn at the pivot.

Each clamp ships with an L-shaped metal screw and plastic nut for assembly. The plastic toolbox keeps all four organized and ready to grab.

Works for four different trades

Picture framers use these all day. Furniture makers reach for them on drawer and cabinet box assembly. Carpenters building small boxes and birdhouses. Even mailbox builders — anywhere a perfect 90-degree hold matters and flex is not an option.

One year warranty and a plastic toolbox so you keep track of all four pieces.
