If you are building machine frames or guarding systems for clean room applications, you should take a look at a new range of radius seals for the Item profile system, which is available in the UK from Machine Building Systems. Radius seals are special caps that seal the end face of the profile in order to prevent moisture and dust ingress. They are located between two profiles that butt together in a right-angle, and are particularly useful for sealing off the corners of a frame construction (illustrated).
