"Had to join a double oven to a cooker circuit. 3 heavy duty cables, this was the only connector I found with the capacity to accomodate 3 thick cable wires in each terminal. Well done Screwfix (again!)"
"This product has a frame which screws to the wall. The frame contains easy-to-get to "slot" terminals which face towards you (not towards the wall as with other designs) - just lay all the wires you want connected into the slot in one terminal and then fit the terminal's clamp screw. The terminals face towards you as you're fitting the wire - no more struggling to poke several thick, uncooperative wires into a hole in a terminal that's facing away from you! When you're all finished just fit the white cover and the job is complete.
Save yourself a load of frustration and get one of these."
"I bought 2 of these to install 2 ovens. The internal connectors unscrew from the back box in a frame making it very easy to connect the wires. It easily took 2 6mm wires in the same hole, which is what I needed.
Just make sure you buy the matching MK pattress box, as the screws are slightly off centre and will not fit with other boxes as I found out!
I've given 5 stars for performance and reliability, but time will tell."
