Uni-Loc® Joint Guide: Quick-Release, Radial, and Steel-Lite

Uni-Loc is a trademarked brand of Predator Group. Uni-Loc brand joints include the Original Quick-Release Joint, Radial Joint, and Bullet Joint. Here is a link to our Uni-Loc Joints: https://uni-loc.com/. Our joints offer the highest level of interchangeability, which means it is easy to fit a new shaft to a cue butt.

Quick Release vs. Radial

The Uni-Loc Quick-Release Joint is by far the most popular joint that Predator offers and is featured in most of our recurring cue lines. This joint type allows the cue to be jointed and unjointed very quickly, in just one and a half turns. That's why it is referred to as quick-release. The pin is smooth, and the brass shaft insert interlocks with the steel channel, surrounding the pin. This fast and convenient joint features a tight, unwavering fit and the characteristic stiff feel of a steel-jointed cue. We recommend cleaning the Uni-Loc Quick-Release joint and facing every six months to maintain proper function, a tight fit, and cue alignment.

In contrast, the Uni-Loc Radial Pin is a good choice for those who prefer a larger, threaded pin, which is featured in a number of Special Edition Cues, including cue maker collaborations. It features 7  threads and requires more time to join and unjoin. The Radial pin is nestled directly into the cue butt, which threads directly into the matching threads inside the wood or carbon fiber shaft. This wood-to-wood or wood-to-carbon fit creates a tighter, desirable feel for some players, but it also increases friction when jointing and unjointing the cue. The Uni-Loc Radial Joint requires less maintenance than the Uni-Loc Quick-Release Joint, and when paired with a Predator Radial shaft, provides flawless compatibility.

Uni-Loc® Steel-Lite Quick Release Joint in Utility Cues

Predator utility cues such as the BK Rush and Air Rush, feature the Uni-loc Steel-Lite Quick Release pin. 

The Preditor Uni-loc Steel-Lite Quick Release pin is a unique joint with a shorter pin than the standard Uni-Loc Quick-Release pin featured on our playing cues. The shaft must be joined with the cue butt with care to align them together correctly, or misthreading may occur. This also applies to break/jump and jump cue handles and forearms. You will need to line the shaft up with the cue butt, insert the pilot end of the shaft into the channel of the pin, and slowly turn clockwise until the thread catches. This shorter pin does not join up as quickly and easily as its counterpart, the longer, Uni-loc Quick Release pin. This is why more care must be taken when joining a shaft to a cue butt, that features the Uni-loc Steel-Lite Quick Release pin.

You may be wondering why Predator chose this pin for their utility cues. This pin was created shorter, to provide a “break balance” feature, which allows weight to be more evenly distributed across the cue. This is one reason why the BK Rush Break Cue offers an optimum break weight of 18.5 ounces, to perform its best when a break is executed at medium speed. This is part of the technology, built into the product.

Uni-Loc® Joint Questions

A Uni-Loc joint is a patented, precision-machined connector that joins a cue's shaft to its butt. Unlike a standard threaded joint, it seats with a controlled turn rather than relying on screw threads alone, giving a tighter, more repeatable fit over the life of the cue.

The Quick-Release joint uses a smooth pin that locks in about one and a half turns, built for speed and a consistent steel-jointed feel. The Radial joint uses a larger, 7-thread pin that seats directly into matching threads in the shaft, giving a tighter wood-to-wood (or wood-to-carbon) feel that some players prefer, at the cost of taking longer to join and unjoin.

The Radial joint appears on select Special Edition cues and cuemaker collaborations, rather than Predator's core recurring lines, which use the Quick-Release joint.

Predator's break and jump cues use the Steel-Lite Quick-Release joint — a shorter-pin variant of the standard Quick-Release joint, built specifically to shift weight distribution for break-cue performance. Playing cues use the standard-length Quick-Release joint instead.

Check the product specifications on predatorcues.com — joint type is listed for each cue — or compare against the joint images on this page. If you're fitting a shaft to a non-Predator cue, our Joint Types by Manufacturer lookup can help identify it.

Predator recommends cleaning and facing the Quick-Release joint roughly every six months to maintain a tight fit and proper alignment. The Radial joint requires less frequent maintenance than the Quick-Release joint.

No. The Bullet joint is part of the Uni-Loc® brand lineup, but Predator does not currently offer it on any cue. Predator cues use the Uni-Loc Quick-Release joint, the Radial joint, or — on break and jump cues — the Steel-Lite Quick-Release joint.
