Even shade-tree mechanics own a set of 1/2″ to 3/8″ drive (and visa-versa) adapters, and hard-core tool guys even own a set of universals. But as anyone who’s used a jointed adapter knows, it’s tough to keep the adapter attached when you’re working it tight spaces — you know, like you always are with universals. MAC recently released a set with a locking collar that keeps it attached.
It still retains all the swivel action you’ve come to expect from this type of adapter, and it features the same high-polish chrome finish you’ve come to expect from MAC.
For pricing you’ll need to contact your friendly local distributor — or chase down one of the trucks. Our guess is that they’re not cheap.
