One-Shot Rat-Trap MK II speaker and grille system
The new design improves even further on what was already the world’s fastest installing speaker and grille combination. The new single piece grille is a revolution in injection moulding, which required a marathon effort on behalf of Altronics designers and plastics machining experts.
The One-Shot Rat-Trap MK II offers installers considerable labour savings.
Altronics field tests indicate a time saving per unit of around 8 minutes, over a traditional screw fixing speaker. This equates to a $6 to $8 cost saving.

Traditionally speaker grilles required screws or special fixings. Many generations later, the One-Shot Rat-Trap has eliminated the need for fasteners thanks to a spring loaded integral clip system which has changed the way sound professionals install commercial speakers.
The grille is paired with the CC2099, a customised 100mm (4″) PA speaker driver and 100V line transformer, offering excellent speech intelligibility for BGM, paging and emergency warning applications. The transformer offers 5 power tappings up to 5W and is fitted with a 4 way terminal block, line monitoring capacitor, transformer cover and cable restraint, as required by the Australian Standard AS1670.4. The driver offers excellent frequency response and SPL of 92.7dB (1W/1m @ 1kHz).
The One-Shot Rat-Trap is a 100% Australian designed and manufactured product and is a registered design. They are used extensively in hospitals, office buildings and shopping centres – anywhere commercial public address or fire and evacuation (EWIS) systems are in use.
