Black Diamond Camalot C4

Black Diamond Camalot C4s are the original double axle design cam. Their incredible strength allows them to be used as a traditional cam or be placed fully open in a crack like a nut. Camalots are the only type of cam that offer this feature.

The double axle provides Camalots with a very large expansion range allowing a smaller number of cams to cover a wide range of crack sizes, meaning less weight for the climber and less trouble selecting the right size cam. Made from super durable aircraft grade aluminium and stainless steel cable, they are built to last.

4 Cam Camalots come in 10 overlapping sizes, fitting cracks from microscopic to cavernous. We stock the sizes 0.3 to 4 which cover the kind of cracks most usually encountered in the UK. We are happy to order in sizes 5 and 6 and it only adds a few days to the delivery time.

Reviewer: Ian, Hertford  

After careful research on range and cost on Cams, I decided upon a BD Camalot C4, in this case a size 2 (to fill a hole (pun intended) in my rack). It is beautifuly engineered, I like the postive thumb loop, this is a little easier to use compared with DMM 4CU for example and very similar to the WC Helium Friend series. Being a twin axled you get a marginally larger range than single axled, meaning a little more overlap between sizes and hopefully more options for placement, but it will be a few grams heavier than the equivalent single. In this respect I am happy with a little more weight, with more flexibility in placement. The Nylon tape used seems a little old fashioned when other Cams have skinny Dyneema, but apparently this will give a longer life. These aren't cheap and its worth conidering DMM Dragon Cams as an alternative. Overall I am likely to fill the further gaps in my rack with Camalot C4's, I have my eye on a Size 5 when I am feeling flush...

Awesome cams - solid, durable, confidence inspiring. For guiding the double axle design is a no brainer - they place and remove faster than a single axle cam and this easily compensates for the small weight penalty.

These are definitely my favourite cams on my rack. I'm always reaching for these ones. The action is smooth and the thumb-hole makes me feel confident. I'm not going to drop a peice. I love the trigger mechanism on this cam and the hold always inspires confidence. I place these cams whenever possible.


  • thumbhole!!!
  • great range
  • nice trigger point
  • double
  • best cams awkward placements


  • the price :( (I'm a student)
  • little heavy

Bought a few of the mid sizes are using the Dragon Cams for a couple of months. They are almost identical besides a few features. These are:

  • The thumb loop, which the Camalots have, and the Dragons dont. This is one of the reasons for me now preferring the Camalots.
  • The cam lobes on the Camalots are also a lot wider, giving that extra secure feel, which is invaluable on hard routes!

The price between them is pretty similar, and the functionality pretty much the same. But if you’re looking for a reason to buy these over anything else, the two above have been enough for me!

Camelots are very well designed and well made. I've used a great variety of cam types and these are my favourites.

Pros: Their greater camming range means that in extremis you can afford to be less accurate with size choice - I often find myself picking the most likely size and then trying it in a few different places within the crack until I've got a really good placement. Also if there's a constriction at the front of the crack you can squeeze the cam down really small to get behind it. The loop at the end of the stem is helpful, especially with bigger sizes, for fumble-moments.

Cons: They are heavier than standard cams, so you can carry fewer for the weight.

Reviewer: Adam Scott, Solihull  

BBuilding up my rack, I took the common advice and bought some Camalots rather than Friends or 4CUs. Greater range than the competition (unless you go for some much more esoteric and expensive designs) make these the obvious choice for either reducing the number of cams you have to carry or increasing your placement options with the same weight.
The flexible single stem design makes placements easy, and the colour coded heads and slings makes picking out the right cam really easy - especially if paired with matching krabs.
The only down-side of the Camelot design is the nylon slings that are used. Much bigger than the svelte dyneema designs that almost all other cams come with, and without the extendible double design used by WC and CAMP. That being said, it's easy enough to stick a QuickDraw on, and the extra wide sling isn't that much of a nuisance in the grand scheme of things.
All in all, after using my Camalots for a fair few months and a fair few climbs, as well as using other people's equipment and comparing, I'd say I made the right choice. If you're looking for a set of cams to start off your trad rack, go for a set of Camalots (I'd recommend starting with 0.5 - 3) and you'll be able to climb pretty much everything you'll come across right up to the E grades.
