Copper Tube Support for Industrial Plumbing

The Dura-Blok DBM-1 is a copper tube support block designed for industrial plumbing installations. It accommodates pipe with a maximum outside diameter of 1 3/8 in and a maximum pipe size of 1 1/4 in. The rubber base measures 4.8 in L x 6 in W and the overall height is 11.63 in. Installers place it on a surface and may glue or anchor it for additional support.

Sustained Load Behaviour with Height Adjustment

The block carries a load capacity of 50 lb across the full adjustment range. Height can be set from a minimum of 10 1/8 in to a maximum of 11 5/8 in so the tube remains supported during long thermal cycles. The split ring clamp holds the pipe firmly without rollers, preventing lateral drift when vibration or expansion occurs over extended periods.

Rubber Base and Mounting Flexibility

The rubber base resists oil, moisture and temperature swings common in mechanical rooms. Because the unit is simply placed on the surface, it can be repositioned before final fixation. Glue or mechanical anchors add rigidity for permanent layouts without requiring specialised brackets. This mounting freedom suits both temporary test rigs and fixed distribution lines.
