The Ancol Chain Coupler is a strong and reliable tool for walking multiple dogs. 
 
The heavy chain is chrome plated for strength and beauty and the coupler has a large O-ring so it may easily be affixed to a lead. Couplers are a must-have for pet owners with two dogs. While walking two dogs used to mean leads, dogs, and owners got tangled, a coupler means just one lead is needed and the dogs are kept together.

The length of each of the Chain Coupler chains, including the trigger hook, is 24cm (approx.). 
 
The maximum recommended weight for this coupler is 2x50kg.
