A tubular cover or metal support members has been provided in which the tubular cover member is made of multiple layers of material such as wood veneer and in which all of the layers are severed to form a slit to extend longitudinally of the tube and in which a hinge point is formed diametrically opposite to the slit by severing all except the outer layer of material. In one embodiment, the hinge is reinforced with a sheet of inorganic material. Applying the tube to the support member entails opening the cover to place it on the support member and fastening the opposite edges of the slit to each other to make a permanent enclosure for the support member.
