Acrylic Tube, Square, Extruded - Clear

Extruded acrylic square tube is a clear hollow square section with flat, parallel faces and consistent wall thickness along its length. The square profile sits flat without rolling and gives a clean face for graphics, labels or bonded joints, which round tube cannot. It cuts, drills and cements with ordinary acrylic solvent cement and flame-polishes to a clear edge. Stock runs from 1/4" through 2 3/4" inside dimension in 1/16" and 1/8" walls.

Square tube is the usual choice for display risers and pedestals, sign and menu holders, light boxes and edge-lit panels, protective covers over instruments, and framework where a square section keys into a bracket. The 1/8" wall sizes carry noticeably more load than the 1/16" and are worth specifying for anything structural. Acrylic is not recommended for continuous contact with strong solvents. Sold by the foot and cut to your specified length, which saves both material and shop time.
