These blocks are good for a lab project and offer good strength even for small gauge wire. If you want to use crimp terminals, use the long ones. Be careful if you have to cut the jumper so that it doesn't stick out of the block and touch adjacent blocks that need to be insulated. This is a practical product but I would not recommend using them in production as they do not have a UL symbol meaning they are unlikely to be UL listed.
