Laguna Tools intorduces the Contractor line by E. Emerson Tool. Which finds itself halfway between Single Series and the Ultra Series of clamps. After conducting research we have found the Contractor Series to be the right clamp for specific markets that have yet to see a straight edge. A Lighter feel than the Ultra, yet twice as rigid as the consumer grade All in One Straight Clamp. E. Emerson’s straight edges already have a low profile but the Contractor’s two T-tracks are recessed to give it an even lower profile.
