With input from Black Diamonds top athletes, the Z4 cam is a single-stem cam that stays rigid in-hand, thanks to the RigidFlex System. This new technology massively increases the ease of placements when sliding the cam in cracks but when the cam has been placed the stem flexes and decreases the chance of the cam walking/adjusting in the crack when being climbed above which makes sure your placement has the maximum chance of holding.
Independently floating trigger is used on the Camalot Z4 which make sure the cam doesn’t bend while under tension and retracted, but once placed allows the stem to move, ensuring a placement that stays put and doesn’t walk when pulled directionally.
The stem on the larger sizes also utilises dual twisted cable construction which provides uniform flex in all directions, while single cable construction is implemented on smaller sizes to avoid buckling when pulling hard on the trigger and to reduce trigger profile.
Featuring a similar head-width as the old BD Camalot C3 design, but with 4 lobes that are sandblasted for better holding power, the Z4’s are not only an upgrade but are also available in smaller sizes. Starting from #0, Black Diamond's smallest cam ever made, and ranging to .75, allowing you to dial in the rack and have a tool for every job.

Buyers Guide To Choosing a Trad Climbing Rack
Excited to be buying the first bits of lead gear to build your trad rack? So are we! The only thing we love more than talking about gear is going climbing ourselves. We don’t just learn about what’s the best kit to use – we know what’s the best kit to use……..
As you climb more, you’ll discover that different routes and different types of rock accommodate different shapes of gear from different manufacturers, so it’s always worth having a mix on your harness. Nuts are ideal for placing in tapered cracks. If you have the means, then the DMM Nut set 3 is a great place to start. Offset nuts offer a different shape, and hex’s are great for protecting parallel cracks. Oh, and make sure you buy a nut key. No one likes leaving shiny new gear on a route.
Having a collection of extenders of different lengths makes life a lot easier when it comes to reducing rope drag. Quickdraw packs can be a cost-effective option, but go for a pack with differing lengths.
A couple of 120cm slings and a 240cm sling will cover most needs. They come in different colours, which can be handy to quickly identify the length.
Karabiner packs offer great value for money. Wiregates are lighter weight, larger karabiners can be easier to handle, some snapgates are designed to lock for added safety, and there is often a choice of bent or straight gate. Bent gate karabiners can be easier to open – but that means an ill-clipped bent gate karabiner can be opened by a rope too, so if in doubt, go with straight gates. You will need some screwgate karabiners for rigging belays as well. HMS style allows for knotted ropes and slings to clip easily.
When well placed, cams like Wild Country Friends, DMM Dragon Cams, BD Camelots, etc, will make a great addition to your rack, protecting parallel and slightly flared cracks. 0.3 – 3 (Wild Country and Black Diamond) or 00 – 5 (DMM) are good sizes to start with.
Carry Prusik Loops! Whether you make your own or buy some Beal Jammies, Prusiks can save you a WORLD of trouble when things don’t quite go to plan. Use one clipped to your leg loop while you abseil to protect from a fall or to take your weight when hair or clothing gets wrapped in your belay device. They are also very handy for getting yourself out of a sticky situation with a scared second, a jammed rope, crossing a rope knot in a 180m abseil and rescuing a cragfast sheep. We speak from experience!
Climbing loads will wear out your lovely shiny new kit. In fact, even if you don’t climb, your harness, slings, extenders, etc, all have a shelf life and will need to be inspected and possibly replaced. There are loads of top tips in the knowledge section of our
Joe Brown Outdoor Academy website on how to inspect your climbing gear.
