Support for tubing and method of using same
A stand formed of two identical halves for holding tubing of different diameter is disclosed. The support has a securing mechanism to secure the two halves at different relative distances from one another. Each of the halves of the stand have a corresponding clamping surface. When the two clamping surfaces of the two halves are secured together with the clamping surfaces facing each other, the clamping surfaces form a clamp to hold the tubing. The two halves can be secured at different relative distances from one another to accommodate tubes of different diameters between the clamping surfaces. The clamping surfaces have an arcuate portion which hold the centre of the tubing a predetermined distance from the base of the stand regardless of the diameter of the tubing. The stand can be attached to a cement form during building construction to hold the tubing a predetermined distance above the cement form.
