12mm Alloy Steel Security Chain 4ft

The Titanker 12mm chain is a vinyl-coated alloy steel cable with braided construction and double end loops. It is designed for cyclists and homeowners who need a flexible, cut-resistant tether for bicycles, gates, grills, ladders or truck-bed cargo.

Double-loop installation with cold-weather stiffness

Each end forms a sturdy loop that accepts padlocks, U-locks or disc locks without extra hardware. The vinyl sleeve prevents frame scratches and rust, but the supplier notes the cable becomes stiff and hard to bend when temperatures drop below 20 to 25 degrees.

Sustained outdoor exposure

The braided steel core and vinyl jacket are built to resist corrosion and abrasion over long periods outdoors. Under continuous load the cable maintains its shape, while the looped ends distribute stress evenly during daily lock and unlock use.

Questions about this item

How can I check the 12mm alloy-steel chain is working properly after I fit it?

Loop the vinyl-coated cable through the double end-loops, attach your padlock or U-lock, and confirm the braided steel moves freely without kinks or rust spots.

What comes with the 4ft chain and what must I supply myself?

The box contains the 12mm black vinyl-coated steel cable with double end-loops; you must provide a padlock, U-lock, or disc-lock to secure the loops.

Which length should I choose among the 4ft, 7ft, 15ft and 30ft versions?

Pick 4ft for a single bike or small item, 7ft for two bikes or a gate, 15ft for multiple pieces of equipment, and 30ft for long runs like truck-bed tie-downs.
