Poison Cues and Extensions

The QR2 Extension Is Not Compatible with Poison Cues

The Predator QR2 Extension is built for cues equipped with the Uni-Loc® Weight Cartridge System — a system Poison cues don't have. Attempting to pair a QR2 Extension with a Poison cue can damage the joint threading and will void your Poison Limited Lifetime Warranty.

Why It Doesn't Fit

The QR2 Extension's bumper is designed around Predator's weight cartridge hardware. Poison cues use a different bumper and joint construction, so even where an extension appears to thread on, it isn't a supported connection — over time or under pressure it can strip threads or damage the bumper housing.

What This Means for Your Warranty

Installing a QR2 Extension on a Poison cue is considered a non-authorized modification. If damage results — to the bumper, joint, or shaft — it falls outside the Poison Limited Lifetime Warranty's coverage for manufacturing defects.
