Simpson Strong-Tie SDE Width Adjustable Joist Hanger SDEG340/30, Left Piece, for 60–250 mm Joists

Simpson Strong-Tie SDEG340/30 is the left piece of the SDE two-piece, width adjustable face fix joist hanger for timber joists from 60 to 250 mm wide.

The SDE system consists of two separate components, a left piece (SDEG) and a right piece (SDED), that are positioned to suit the joist width. One hanger therefore covers a wide range of joist sizes in both new build and refurbishment work. Use SDEG340/30 together with the matching right piece SDED340/30.

The hanger is made of galvanised steel S250GD + Z275 (EN 10346). It has optional bolt holes (Ø 13 mm) and can be fixed to a timber, concrete or steel supporting member.
