The Castair Cable Clamp (threaded, part number 0817) is a small but essential hardware component used in air compressor installations. This is a threaded cable clamp — the kind of part that gets ordered as a replacement or as part of a system build and tends to be forgotten until the job stalls without it. If you are wiring up a Castair compressor or replacing worn mounting hardware, this is the correct part to have on hand.
\n\nWhat This Part Does
\nCable clamps are used to secure electrical conduit, wiring, or control cables to the compressor frame or enclosure. The threaded design allows it to be fastened directly through a mounting hole with a corresponding nut, providing a secure, vibration-resistant hold. This matters on air compressors, which generate significant vibration during operation — a loose cable can chafe against metal edges, damage insulation, or work free entirely over time.
\n\nWhere It Is Used
\n- \n
- Compressor frame wiring: Securing motor power leads and control wiring to the frame \n
- Panel installations: Mounting conduit or cable bundles to magnetic starter enclosures \n
- Pressure switch wiring: Keeping control leads organized and protected near vibrating components \n
- Replacement maintenance: Replacing corroded or broken clamps on existing Castair installations \n
Why Threaded vs. Standard Cable Clamps
\nThreaded cable clamps (also called conduit connectors or locknut-style clamps depending on application) pass through a punched or drilled hole and secure from the opposite side with a nut, rather than clamping onto a surface with screws. This gives a cleaner installation with the clamp flush to the panel or frame, and it is generally more secure against vibration than surface-mounted alternatives.

When Does a Shop Need This
\nYou need this part when you are replacing damaged or missing cable clamps on an existing Castair compressor, completing a new installation that is missing this hardware, or sourcing OEM replacement components for a Castair unit under warranty. Threaded cable clamps are not universal — using the wrong size can result in cables that do not seat properly or damage to the cable jacket. If you're doing a full install, Castair's Right From The Start kits (RFS001, RFS002) cover the major consumables, but individual hardware like this clamp is ordered separately as needed.
