"I bought this after reading the previous reviews, both on this and rival products, and I was not disappointed. It is easy to fit 4 cables of 1.5 sq mm. into the junction box and, crucially, the terminals are of good quality. I bought 4 boxes and I had no fitting problems. I have many Crabtree switches and connectors and I have no doubt these will be as reliable as their predecessors. Don't be tempted to save a few pence and buy the cheap alternative."
"When replacing my upstairs lighting circuit I used half a dozon of these Junction Boxes. They are well made, well sized and easy to work with. The terminals allow for a variety of cable sizes and clamp well."
"These junction boxes are perfect for lighting systems where it is impracticable to terminate all the cabling within the light fitting itself, such as fluorescent lighting or light fittings with small ceiling roses."
"Quality good but small screw terminals. Can only accommodate 3x 1.5mm or 4x 1mm cables. Smaller than an HD JB but not small enough to go through a down-lighter hole. Hmmm. Why don't Screwfix do a 20amp Heavy Duty 4 terminal junction box. They have 3 terminal 30amp and 6 terminal 20amp but not the basic 4 terminal HD?"
