Description
Pulling cable through conduit is a two-part problem. The first part is force, and the second is damage. A grip that holds too loosely slips and scores the insulation. A grip that bites too hard crushes the conductor. The wire mesh pulling sock exists because it solves both at once, and it has not been meaningfully improved in fifty years because the principle is already correct.
The Cable Sock is a galvanised single-wave mesh that tightens under load. Feed the cable into the open end, pull the eye, and the mesh contracts around the jacket in proportion to the tension applied. The harder the pull, the firmer the grip, and the load spreads across the full mesh length instead of concentrating at one bite point. That is how a 470 mm sock handles a 20 to 25 mm cable without deforming it.
Six sizes cover the working range: 220 mm for 4 to 6 mm cable, 260 mm for 6 to 10 mm, 300 mm for 10 to 12 mm, 370 mm for 12 to 15 mm, 390 mm for 15 to 20 mm and 470 mm for 20 to 25 mm. Colour coding is applied by size, so a technician reaching into a toolbox in a riser cupboard can identify the right sock without reading a label.
The galvanised finish is the detail that decides service life. Bare steel mesh rusts at the eye after a few damp pulls and then fails exactly when the load is highest. Galvanising costs little at manufacture and buys years of use in ducts, trenches and outdoor runs, which is why electricians and telecom technicians both keep a set in the van.
The tool that never gets photographed is usually the one that gets the cable through the wall.
Why It Works
- ✦ Single-wave galvanised mesh tightens grip proportionally to pull load
- ✦ Six size-coded socks covering 4 mm to 25 mm cable
- ✦ Load spreads across the full mesh length, not one bite point
- ✦ Protects cable insulation from scoring and crushing
- ✦ Galvanised finish resists rust at the eye and in damp ducts
- ✦ Colour-coded by size for fast identification on site
- ✦ Suits electrical, telecom and conduit installation work

Where It Belongs
Electricians pulling armoured cable through a riser use the 470 mm sock on the heavy end and a 220 mm sock on control wiring in the same run. Telecom technicians pulling fibre use the smaller sizes because the mesh protects the jacket from the abrasion that causes attenuation faults months later. Maintenance crews in plants keep a full colour-coded set on the cart, since a mismatched sock that slips means re-pulling an entire conduit length.
Questions Buyers Ask
Q: How do I match a sock to my cable?
A: Measure the outer jacket diameter, not the conductor. Choose the sock whose stated range brackets that figure, and size up if the jacket is armoured.
Q: Does the mesh damage insulation?
A: No. The load is distributed along the mesh length, so the jacket is gripped rather than point-loaded. Slip only occurs when the sock is undersized.
Q: Can it be used on fibre optic cable?
A: Yes, with the correct size. The mesh protects the jacket, which is where fibre pulls usually fail.
Q: What is the maximum pull load?
A: Each sock is rated for its size class. Pull within the rating and inspect the eye for deformation after any heavy pull.
Q: Will it rust?
A: The galvanised finish handles damp ducts and outdoor runs. Store dry and wipe after wet work to extend life.
Q: Is one sock enough for a job?
A: Most crews carry three or four sizes, because a pull usually involves more than one cable diameter.
