Metallics SPN38 – Frequently Asked Questions
1) What size cable or conduit does the Metallics SPN38 clamp hold?
The SPN38 is a 3/8 inch insulated cable clamp, so it is sized for cable or small tubing runs with roughly a 3/8 inch outside diameter. Seat the cable in the opening and snug the clamp without crushing the jacket; an undersized clamp forced over a larger cable deforms the steel band and loses its grip.
2) Why use an insulated cable clamp instead of a plain metal strap?
The neoprene wrap on the Metallics SPN38 puts a cushion between the steel band and whatever it is holding. That does two things a bare strap cannot: it keeps dissimilar metals from touching, which is where galvanic corrosion starts, and it gives electrical separation between the cable and the mounting surface. It also keeps the band from biting into a cable jacket under vibration, which is why these get used on HVAC and equipment runs.
3) How many clamps come in a bag, and can I buy just a few?
The SPN38 ships as a 20-pack in a bag, and 20 pieces is the order minimum. If you only need two or three for a panel, you are still buying the bag, but for a multi-opening or multi-unit job the bulk bag is the point.
4) Can the same clamp be used on plumbing and HVAC lines, or is it electrical only?
Metallics lists this clamp for the electrical, plumbing, heating and air conditioning trades. In practice that means low voltage and branch cable at panels and junction boxes, control cable on plumbing and boiler equipment, and sensor or thermostat wiring on HVAC units. It is a support clamp, not a pressure-pipe strap, so size it to the cable or small tube diameter rather than to nominal pipe.
5) What does the SPN38 clamp look like once installed, color wise?
Silver and black: bright steel band with the black neoprene wrap showing where it contacts the cable. For exposed runs in finished spaces that reads as standard mechanical hardware rather than something you would try to match to a wall finish.
