2 x 5-Way DP 100A Service Connector Block 35mm² is rated 4.0 out of 5 by 9.
Rated 4 out of 5 by from Connector block Bought this to connect two 25 mm tails together during a consumer unit change and found these make a rearly good job of it.Have two connector blocks with heavy duty screws that you can apply good pressure to.

Rated 5 out of 5 by from Good block feels brittle Excellent block, used for supplying 2 consumer units with 25mm tails- note that screws need to be backed right out to accomodate 25mm tails ( i removed screws completely to ensure i could see that the copper was fully seated in both screw holes then re-inserted screws very tight as I was paranoid they would drop out.) Had no issues

Rated 3 out of 5 by from brittle cover Solid connection blocks and does the job OK but the lid is brittle and was already broken on my purchase

Rated 4 out of 5 by from great for adding second board heavy duty brass blocks, drill out holes with a 10mm hss bit, hole for seal, nice tidy box for a pro job

Rated 3 out of 5 by from Careful - they're fragile Holes drill out easily enough, but it would be nice to have some markings indicating how much to strip back the cable. Don't try to force anything - the material is very brittle and cracks easily.

Rated 5 out of 5 by from just the job needed to link two consumer units this was just the job for what i wanted to do
Date published: 2014-06-18
Rated 4 out of 5 by from Fast easy install After struggling with the existing one on a job I installed this instead found it easy to fix knock outs are hard but 10mm drill bit on it takes it out clean it fits 25mm tails comfortably with other sheath. The previous comment said the entry holes were only 9mm mine were at least 10mm was probably talking about the 25mm not this 35mm one.
