Red and black push-in speaker terminals with two positions, spring-loaded design, 42 mm square footprint, 31 mm hole spacing, and 3.3 mm mounting holes in a pack of ten
These spring-loaded speaker terminals come in a pack of ten pieces with red and black colour coding for polarity. Each board provides two positions for secure wire connections in custom speaker builds or upgrades. The push-in design simplifies installation without requiring soldering or screw terminals.
Verify that your enclosure or panel can accommodate a mounting hole diameter of 3.3mm with a centre-to-centre spacing of 31mm. The overall board measures 42mm by 42mm and has a depth of 17mm behind the mounting surface. Ensure the available clearance matches these dimensions for a proper fit.
The spring-loaded mechanism grips bare wire instantly when inserted and releases with a simple press. This eliminates the need for crimping ferrules or tightening screws during assembly or maintenance. The two-position layout keeps positive and negative leads organised on each board.

The pack contains ten push-in speaker terminal boards, each with two spring-loaded positions for bare wire. Mounting screws are not supplied, so you will need 3.3 mm hardware for the 31 mm centre-to-centre holes.
Every board in this set is identical — two positions coloured red and black — so a single board handles one speaker’s positive and negative leads. Buy the 10-piece pack if you are wiring multiple cabinets or want spares.
Each board measures 42 mm by 42 mm with a 17 mm depth behind the panel, and the mounting holes sit 31 mm apart centre-to-centre.
