20pcs 1 Inch Stainless Steel Cable Clamps, Rubber Coated, Black
20pcs 1" Stainless Steel Cable Clamps — Rubber Coated OURU Insulated P‑Clamps
Secure, vibration‑resistant cable management for demanding indoor and outdoor projects. These 1" (25 mm) OURU cable clamps combine marine‑grade 304 stainless steel strength with a cushioned rubber lining to protect wires, hoses, and tubing from abrasion and vibration.
Why choose OURU rubber‑coated P‑clamps?
Durable stainless construction
Each clamp is made from 304 stainless steel — corrosion resistant and built to withstand harsh environments including moisture, salt spray, cold and heat.
Rubber insulated cushion
The nylon rubber lining cushions wires and hoses against vibration and abrasion, preventing chafing and electrical insulation damage.
Easy to install
R‑shaped design and a screw hole that fits a 6M (1/4") bolt make installation quick — reposition or remove clamps easily with a screwdriver and standard screw.
Ready to store & reuse
20 clamps come in a compact storage box for easy carrying and reuse across multiple projects.

Installation guide — quick steps
- Choose the clamp size that matches your cable, hose, or tube (this kit fits 1" / 25 mm).
- Position the clamp around the cable or tube, making sure the rubber cushion sits between metal and the line.
- Align the clamp hole to the mounting surface and insert a 6M (1/4") screw or bolt through the hole.
- Tighten the screw until the clamp holds the cable firmly but does not compress the rubber excessively.
- Check routing to prevent sharp bends and allow for thermal expansion or movement.
Tip: For marine or corrosive environments, use stainless screws or bolts to match the clamp's corrosion resistance.
Ideal applications
These clamps are perfect when vibration, moisture, or abrasion are concerns:
- Automotive wiring harnesses, fuel lines, brake lines (where routing protection is critical)
- Boat rigging, bilge pump lines and marine electrical runs
- RVs and trailers — secure plumbing, wiring and gas lines
- Workshop equipment, machinery and industrial cable runs
- Home use — neat cable organization behind entertainment systems or networking racks
Frequently asked questions (FAQ)
Will the clamp fit my cable?
This kit is sized for 1" (25 mm) internal diameter. Measure your cable or hose diameter before installation — the rubber cushion will accommodate minor size differences but is not intended for much larger diameter lines.
Are screws included?
Screws/bolts are not included. Use a 6M (1/4") screw or bolt appropriate to your mounting surface — stainless recommended for outdoor/marine use.
Can I use these clamps outdoors?
Yes. The 304 stainless steel body resists rust and corrosion, and the rubber cushion withstands temperature changes and vibration. For long life in saltwater environments, pair with stainless fasteners.
