Double Straight: The Mid-Seam Profile
A double track that joins two fabric fields in the same plane. Both edges tuck into one profile and meet as a seam about 1 mm wide - the solution wherever a wall runs longer than the fabric width.

Tensioned, Ruler-Straight
This is the difference between a stretched wall and an upholstered one. The track pulls the cloth to an even tension across the whole field - no sag, no waves, none of the puffy look of traditional fabric walls. The surface is flat and crisp, with the precision of an architectural finish and the warm depth of textile.

1 Inch (25.4 mm) Rigid uPVC
Extruded uPVC profile, 25.4 mm deep, with a double jaw that takes two fabric edges. Supplied in 5 ft (152 cm) sticks and priced per running meter. Cuts with a miter saw and fixes with screws or staples to drywall, wood or furring.

ASTM E84 Class A, Under 0.1% VOC
Class A flame spread and near-zero emissions - the same profile is specified for a home cinema, a recording studio and a public lobby.

Serviceable by Design
The jaw locks the fabric under full tension and reopens without damage. Swap a stained cloth, open a wall for cabling or re-tension after years - the track stays on the wall, only the fabric moves.

Plan the Run
Place it wherever a wall runs longer than the fabric width and the seam should stay silent. Close the perimeter with Single Straight; a typical stretched wall uses about 1.5 m of track per m².
