Designed for high frequency usage the V290-LD3 & HD3 profiles was designed specifically for the use in exhibition stands, small structures and for projection screens. Also known as triangular or tri-lite truss, straight components come in lengths varying from 1 to 5 meter pieces and are available in Light Duty(LD) and Heavy Duty(HD) configurations. Corners and curves can be made in 3 different apex configurations namely apex up, in and out. Whilst we produce all three variations the apex up is the most common, see V290 Corners.
