Nite Ize SlideLock Carabiner Stainless Steel — Black

The Nite Ize SlideLock Carabiner is a flat-profile stainless steel auxiliary carabiner available in four sizes. Size #4 — 78x50x11 mm, weighing 29 grams — is designed for belt loops, backpacks and light gear carry, with a stated maximum load of 34 kg.

The flat profile sets this carabiner apart from conventional round-wire models: it sits lower in a pocket, clips onto small-diameter objects that a tubular carabiner would not fit, and keeps overall bulk down without giving up strength. The SlideLock mechanism is the other defining feature: a sliding collar that drops over the gate with a single motion, preventing accidental opening during movement. No rotational pressure, no active attention required — it opens when you want it to and stays closed in the meantime. The trade-off compared to a screw-lock carabiner is speed: the SlideLock releases in a fraction of a second, but offers less resistance to sustained lateral force than a threaded collar. For key rings, pack attachments and quick gear organisation it is the right tool; for dynamic loads or prolonged vertical use it is not.

Stainless steel ensures corrosion resistance in wet conditions and continuous outdoor use, without the oxidation issues common to painted aluminium carabiners. Note: the manufacturer explicitly states that this carabiner is not intended for climbing or any application where a failure could cause injury or material damage.

Key points

• The flat profile reduces pocket bulk and clips onto narrow-diameter objects where a tubular carabiner would not fit.
• The SlideLock collar engages in a single movement and stays in place during activity, with no accidental openings.
• Stainless steel: no corrosion in wet environments, intensive outdoor use or exposure to the elements.
• Stated load of 34 kg in size #4 — adequate for gear carry, backpacks and belt organisers.
• 29 grams: negligible in any loadout, there when you need it.
