Fall arrest connectors for high-altitude body harness are key components of safety equipment for working at heights. They are used to connect 

to other safety equipment (such as safety lanyards, energy absorbers, safety ropes, anchor points, etc.). 

Here are some common safety hardware components used as connectors in fall arrest systems.

Scaffold hook: Also called safety snap hook, it is made of alloy steel or aluminum alloy, with autolock design and  large opening 55-65mm, the 

minimum breaking load 25kN.

Carabiner: Made of aluminum alloy or steel, with screw lock or autolock door. Oval carabiners, d shape climbing carabiners and pear shape 

carabiners are some common fall arrest hardware.

Harness Buckle: There are different kinds of harness buckles,such as tongue buckle, mating buckle, quick release buckle. With 45mm inner 

diameter, they can connect the 45mm webbing strap and adjust the lenth of webbing.

Rope Grab: Designed for kernmantle rope, featuring rollers or a gripping mechanism. It's a very important component when working at height 

because it can lock quickly in an emergency to prevent the user from falling.
