Herman Sprenger ULTRA-PLUS prong collar - single ring - stainless steel - 52 cm / 3.2 mm

The classic Herman Sprenger ULTRA-PLUS prong collar in the 52 cm length, with a single fixed ring for the leash and a ClickLock buckle. This is the silver version, without the black galvanic coating, so the steel colour stays stable for the whole life of the collar.

Construction

Made of stainless steel - resistant to corrosion and moisture, smoothly polished. The prongs sit evenly around the dog's whole neck, so with correct use they give a precise cue without excessive pressure in any single spot. A 3.2 mm wire and 4 cm links are the standard size for medium and larger dogs.

The ULTRA-PLUS system

ULTRA-PLUS is a length-adjustment system based on an even number of links - you add or remove links in pairs, and each change shifts the circumference by 8 cm. That way the collar fits precisely to a particular dog's neck.

ClickLock buckle and single ring

ClickLock is Sprenger's patented buckle - one-handed, holds firmly under load, won't release by accident. On this model it sits at the top of the collar. The leash clips into the fixed ring by the buckle - one ring, not two. It's the version preferred by some trainers who want a simpler, cleaner line to the collar.

For on-leash work only

This prong collar is intended for on-leash work during active training. It should not be used during free running, transport or while the dog is unsupervised.

Not sure this size is right?

A prong collar should sit snugly just below the dog's jaw, without sagging - that's how we size it. If you're not sure how to measure the neck, drop us a line and we'll help you choose.
