Specialised custom cable clips for Round cables Nail in pins for use in concrete,  stone and wood.

Why A4 Stainless?

Zinc Plated masonry nails are temporarily corrosion resistant, when corrosion sets they;
  • Create unsightly rust streaks down walls spoiling expensive exterior paintwork and stonework particularly in coastal areas. The A4 grade stainless steel is essential.
  • Difficult to remove without causing masonry damage,  
  • When they snap off the embedded nail continues to ruin paintwork, 
  • Unclipped cables under strain are then prone to failure.  

Utilising corrosion resistance A4 Stainless Steel screws,  no more rusty streaks  , 

  • Complete fixings 

Installation Method

  • Concrete, brick and stone -  require a 5 mm plug. 
  • Wood & Plastic Obviously a plug is not required into these softer materials.

Conclusion 

A more expensive and time consuming method, however a permanent fixing solution which will not spoil exterior walls etc. 

Plain Zinc plated Steel fixings on exterior walls are temporarily rust resistant, 


IF HAVING OUTSIDE WORK UNDERTAKEN ALWAYS INSIST ON STAINLESS STEEL FASTENERS.

Step-by-Step Fix for rusted nails
Follow these steps to eliminate the streaks and prevent them from bleeding through fresh paint:
1. Treat or Remove the Nail
  • If heavily corroded and will not extract : Break off the nail and use a 5 mm core drill to drill out the rusting pin entirely.
  • This hole can then be used for a wall plug
  • If the clip is loose: Remove the old clip, drill a 5 mm hole, and replace it using either a stainless steel pin (4 - 11 mm)  or screw 12 - 28 mm with the appropriate wall plug.

  • Remove the rust marks.
Never paint directly over rust; the orange streaks will bleed through standard emulsion. []
  • Paint or dab the exposed nail head/hole with an oil-based stain blocker or primer, such as Zinsser B-I-N.

4. Paint the Wall [1]
  • Prime the filled patch with a light coat of wall paint, then finish with 1-2 coats of your wall's emulsion paint to match the surrounding finish. []
Preventing Future Streaks
If you are running new cables or replacing old ones, avoid standard zinc-plated masonry nails. Instead, use A4-grade stainless steel or high-quality brass pins/ screws, silicone Bronze etc...which are highly corrosion-resistant and won't streak. [1]
