Strong and light, the Premium Quality profile continues to be asked for by artists. We have maintained this tradition by producing the profile in clear grade, kiln-dried Hoop Pine sourced from plantations in Queensland. Clear grade means that the timber is supplied free of knots. Hoop Pine is a superior timber to Radiata and other pine species commonly used for stretcher arms, as it is less prone to warping. These stretchers are laminated and finger jointed for added stability.
