The rockX Screwlock is the latest addition to the pint-sized line of rockX accessory/utility carabiners. Already handy as a 5 kN (1124 lbf) MBS non-PPE connector, the addition of the screw-lock mechanism turns this diminutive device into a big helper when you need the additional security of a locked gate. With a frame machined from solid aluminum, the rockX features contours along the top and bottom profile for ease of handling.
