Black Square Key Clamp Double Lugged Bracket for 25mm Box Section, Indoor Use

The black square double lugged bracket fixes a board, panel or sign to 25 x 25mm box section, with a fixing hole above and below the frame member. A square collar slides onto the box section and locks with one grub screw. Behind it, a flat plate runs out on both sides with a 10mm hole near each end, so the board is screwed or bolted to the plate at two points. It is the neat way to hang boards, mesh, signs and shelves on a box section frame without drilling the steel. It is malleable cast iron with a black electrophoretic finish, for indoor use only. The price shown is for one bracket, with a minimum order of 10.

Why use a double lugged bracket

No drilling the frame. The collar clamps round the box section, so the steel keeps its finish and the bracket can be moved up or down until the board sits right.

Two fixing points. A hole above and below the frame member holds a board firmly, without the twist you get from a single fixing.

Square collar, no spinning. Box section cannot turn in a square collar, so the plate stays flat to the board once the screw is tight.

A dark, tidy finish. The black electrophoretic coat suits shop fitting, display frames and furniture, and is for indoor use only.

Where it is used

Shop fitting and display stands, office and reception partitions, café and bar frames, garment rails, shelving, tables and furniture, and any indoor frame built from 25 x 25mm box section.

Specifications

Which bracket do you need?

To build the frame itself, the square 25mm range includes the short tee, top corner, mid corner and rectangular base.

How many do you need?

Two brackets per board on each upright it spans is usual: one near the top and one near the bottom. A board across two uprights normally needs four.

Choosing the right size

Square key clamps are sized by the outside of the box section. This bracket suits 25 x 25mm box only: measure across one face. It will not grip round tube.

Fitting and care

Slide the bracket onto the box section with the plate facing the board, set the height and tighten the grub screw with a hex key. Hold the board in place and fix it through both holes with screws or bolts to suit the board (not included). Check the screw and fixings after the first week and once a year, and touch up scratches with black paint.
