Snap wire into place with a clamp instead of fussing with a screw. Release the spring clamp with a screwdriver, insert the wire, and push the clamp back down for a secure hold. For an easier fit in the small gaps in the block, attach a ferrule, pin terminal, or blade terminal before installing.

Mounting Adapters—Install terminal blocks on DIN 3 rail with these mounting brackets. You can mount two-circuit terminal blocks with one adapter. For all other blocks, you'll need two.
