Fire Brigade Snap Hooks – what to choose?

You can clip a fire brigade snap hook with one hand, even in gloves: press the gate, hook on a rope, strap or chain, and the spring-loaded gate snaps shut by itself when you let go. For dry use, galvanised steel in lengths of 40–140 mm is fine; for outdoors and damp conditions, choose AISI 304 stainless steel in lengths of 50–100 mm. You will find more shapes among the stainless steel carabiners.

Alongside the snap hooks with a spring-loaded gate, you will also find the oval Kong® Classic with a screw-lock gate.

Parameter guide

What the parameters mean and how to choose the right values.

The dimension of the whole piece, end to end. It tells you how much room the fitting takes on the finished item; what size of ring it can clip onto depends on the gate opening. The whole piece is measured, not just its working part, so two pieces with the same gate opening can differ in length.

Gate opening indicates how wide the gate opens. It determines the maximum diameter of the ring or D-ring it can clip onto.

The diameter of the round wire the snap hook is bent from. Thicker wire takes more load, but the hook is heavier and bulkier. You will find the breaking load listed for each variant.

Frequently asked questions

The most common questions – materials, selection and practical tips.

What matters is the gate opening, meaning how wide a gap the gate leaves when you press it. Your rope, strap or chain link has to pass through it with room to spare. A 40 mm snap hook opens 6 mm, a 60 mm one 8 mm, a 100 mm one 13 mm and the largest, 140 mm, opens 21 mm.

The breaking load grows with length too: a galvanised 40 mm snap hook holds 65 kg, a 60 mm one 250 kg and from 80 mm upwards 500 kg. The breaking load of the stainless steel ones is 450–500 kg. You will find the breaking load for each length in the variant details.

We do not recommend it for a lead. A fire brigade snap hook has no swivel eye for the webbing, so the lead twists as the dog moves, and it is less convenient for clipping to a collar every day.

For a lead, choose one of our dog lead clips.

No. The name “fire brigade snap hook” describes the shape, not a certification. Snap hooks with a spring-loaded gate are not intended for climbing, work at height or securing people.

For securing people, choose only a carabiner with the appropriate certification and follow the intended use of the specific model. In this category, the oval Kong® Classic has EN 362 and ANSI certifications.

In the gate and the breaking load. A regular fire brigade snap hook only has a spring-loaded gate that snaps shut by itself. The Kong® Classic also has a screw-lock sleeve that prevents it from opening accidentally.

The breaking load of the Kong® Classic is 2,400 kg; for regular fire brigade snap hooks it is 500 kg at most.

Where you want to secure the connection after clipping in and do not unclip the snap hook often. Screw the sleeve shut after clipping in and loosen it before unclipping; it does not lock by itself.

Opening and closing therefore takes longer. Where you clip and unclip several times a day, a snap hook with a spring-loaded gate is quicker.
