Perfect for the job
Good solid compact units for bridging several battery cables in a convenient location on vehicles or home generators.

Great Battery Post Connectors!!
Have an auto battery powered race bike starter that has the space in the device for the heavy battery to set in. Of course, that situation makes it very heavy and hard to move around even with the inadequate wheels on the unit. For ease of transport and use, I worked up a remote battery connection with heavy duty fittings using these beauties on the starter side that connected the remote battery from outside the framework. Now both items could be handled separately and connected at the track in lieu of looking for a hernia lugging or dragging a heavy one-piece unit from place to place. The added benefit is that the heavy battery should be removed from the starter for recharging to ensure no damage to the unit when getting ready for the next race location. Now I can set up the starter, connect the battery remotely and let the starting and racing begin!! These battery posts were easily mounted with the included screws, of durable and electrically safe material and of great value for the money!!

Quality...speed of delivery ...Price is right....
These binding posts are suitable for connecting two lugs well....the length would be even better adding 3/8 inch more for more versatility on applications...
