Mastercams are Metolius' timely answer to the famous CCH Aliens. Featuring an extremely narrow head so the device fits in unusual pods and pockets much better than most cam designs. Mastercams have the same camming angle as other Metolius cam units for the very best holding power. Mastercams feature cam stops and a colour-coded dyneema sling.

With Aliens now unnavailable in the UK MasterCams are the high performance cam unit for serious users.
