⚡ At a Glance
- • Reach and access: Thin head and small profile reach tight placements that are otherwise hard to clean
- • Best for: Trad climbers who clean their own placements and need basic maintenance tools
- • Not ideal for: Sport-only climbers who never carry extra rack tools
Compact, purpose-built tool for cleaning placements and performing simple bolt maintenance. Durable stainless steel construction keeps the design practical for regular use.
Protects hands while tapping out jams – with a rubber handle
A moulded rubber sleeve covers the handle to absorb impact when striking the end to retrieve stuck gear. The soft surface reduces abrasion compared with bare metal contact.
Reduced bruising and fewer sore palms after cleaning awkward placements, useful on long routes or exposed leads.
Reach tight placements – with a thin, small head
Slim head profile and narrow shaft allow access into constricted cracks and placements that bulkier cleaners cannot enter. The small head improves precision when levering or hooking stuck protection.
Cleaner access to jammed nuts and cams in narrow placements, lowering the need for more invasive removal techniques.
On-route bolt maintenance – thanks to integrated 17mm spanner
A 17mm spanner is located beneath the rubber handle, sized to fit most bolts for emergency tightening and basic adjustments. The spanner stows neatly to avoid snagging on a harness.
Quick tightening of loose bolts and simple repairs without carrying a separate wrench, helping to keep routes safer during a session.
