Metallics SPN78 – Frequently Asked Questions
1) What size cable or conduit does the Metallics SPN78 clamp hold?
The SPN78 is a 7/8 inch cable clamp, so it is sized to the 7/8 inch outside diameter of the cable or conduit run it secures. Match the clamp size to the OD of what you are strapping, not to a trade size you read off a fitting.
2) Does the Metallics SPN78 clamp have a cushion, or is it bare metal against the cable?
It is a neoprene-wrapped clamp, so the band that contacts the cable is cushioned rather than bare steel. That is what you want on jacketed cable, tubing, or anything you do not want chafed or deformed where the strap bears on it.
3) Is the Metallics SPN78 a one-hole cable clamp or a two-hole strap?
The SPN78 is a single cushioned loop clamp with one mounting hole, the style you fasten with one screw, bolt, or anchor into the mounting surface. Fasteners are not part of the clamp, so pick the screw or anchor for the substrate you are landing on.
4) Can I use a neoprene-wrapped clamp like the SPN78 instead of a standard EMT strap?
Different jobs. A plain one-hole EMT strap is sized to rigid conduit trade sizes and clamps metal to metal. The SPN78 is a 7/8 inch cushioned clamp, better suited to flexible cable, MC, tubing, or runs where vibration and jacket protection matter. If you are strapping EMT to a spec that calls for a conduit strap, use the strap in the matching trade size.
5) Is the Metallics SPN78 clamp steel?
Yes, it is a steel-bodied clamp with the neoprene wrap on the cable-bearing surface. Steel band with a cushion is the usual choice for interior mechanical and electrical support where you need strength plus isolation at the contact point.
