Herm Sprenger Stainless Steel Dog Collar Extension Links, 4.0 mm 3-Pack, Ultra-Plus

Herm Sprenger additional prong links are a set of three 4.0 mm stainless steel middle links designed to lengthen a compatible Ultra-Plus dog training collar.

• Three additional middle links — add length to a matching collar.
• 4.0 mm stainless steel wire gauge — made for collars with the same gauge.
• Compatible with two Ultra-Plus collar styles — choose the version with a Center-Plate and ClickLock buckle or assembly chain.
• Individual links attach to the collar — adjust its length for a custom fit.
• Made in Germany — produced with German engineering.

When a dog’s original Herm Sprenger collar needs more length, these additional middle links provide a way to adjust that collar rather than replace it with a different size. They are made for owners who need to enlarge a compatible stainless steel Ultra-Plus collar and want to make the adjustment by adding links.

What comes in the Herm Sprenger link set?

The set contains three stainless steel middle links with a 4.0 mm wire gauge. These are additional pieces for enlarging a matching stainless steel Herm Sprenger prong training collar; they are not a different gauge intended to match a different collar wire size.

• Quantity: three middle links.
• Material: stainless steel.
• Wire gauge: 4.0 mm.

Which Ultra-Plus collars are compatible?

These links are compatible with the Ultra-Plus Training Collar with Center-Plate and ClickLock buckle, and the Ultra-Plus Training Collar with Center-Plate and assembly chain. Match the links to the collar’s 4.0 mm wire gauge and stainless steel construction before choosing them.

• For the Center-Plate model with ClickLock buckle.
• For the Center-Plate model with assembly chain.

How do I use the links to adjust collar length?

Attach additional individual middle links to the original collar to increase its length and create a custom fit for your dog’s neck. The adjustment is made by adding links to the collar, so the set is intended for lengthening a compatible collar.

• Add individual middle links as needed for the adjustment.
• Use with the original matching collar.

This set suits dog owners whose compatible 4.0 mm stainless steel Ultra-Plus collar needs additional length, including owners of either specified Center-Plate style. Its purpose is collar adjustment through added middle links, not a standalone collar.
