The new QR Extension2 12in. from Predator pairs with any Predator Cue equipped with the Uni-Loc® Weight Cartridge System. Once installed, the quick releasing extension adds an additional 12″ (30.48 cm) of butt length with a single turn of the extension handle. Simply remove your existing rubber bumper, install the Uni-Loc® QR Extension2 bumper using a standard 6mm allen wrench, twist on the QR Extension2 handle and you’re ready to go. Compatible with all Predator, Poison and Molinari cues made since 2012.
