Tie Down's Speed Wrench simplifies anchor installation with a design that allows one-handed operation for installing slotted bolts and tensioning strap. The Speed Wrench has a 15/16” (24 mm) impact socket on one side and a 15/16” “nut” on the other. Combine this with your own ratchet and 15/16” (24 mm) socket and you have the fastest way to tighten slotted bolts!
