    Light weight

    This is clearly quality made. Most others that I have purchased are bulky and heavy. My crews have been beating on these adaptors with 3/8" impact guns and we are yet to break any of them! I am very pleased.

    Just the ticket for my purposes. Quick release work swell and offers good side clearance without interfering with adjacent parts.

    This is solid hex adaptor. It is light weight and durable. Engraved with tool number so that can be placed in a shadowed box and easily be identified. A great idea for a tool! Super handy.
