I agree, Crabtree are the best. A further handy tip is that the Mk 50A isolator and Crabtree screwdriver positions are different by 90 degrees.I prefer the Crabtree, they are easier to fit giving a little more room to maneuver 10mm cable into position. They also have a deeper feed in for the cable & if I remember correctly 2 securing screws per 'pin'. I would always prefer to fit a wall mounted isolator but few customers will (understandably) wear the additional cost of chasing, plastering etc.
If some muppet has fitted either of them in a certain orientation right next to a wall it is almost impossible to tighten the back screws and it's always better to swap to the other brand.
