The Labour Saving One-Shot® Mounting System

Redback® “One-Shot®” speaker units install in seconds providing substantial labour cost savings for the professional installer compared to traditional mounting methods. The “Rat-Trap” version is the first “One-Shot®” to utilise a retaining 3 way spring latching system. Each latch is set like a rat trap before installation into the speaker hole. When the speaker is pushed into the ceiling, the latches spring open, securing the speaker in place. The snap clip material is formulated to retain long service life strength and spring action, ensuring a firm vibration free fit to either gyprock tiles, mineral fibre tiles or fixed gyprock ceilings.
