Profile: Tubeclamps Ltd. manufactures tubular fittings. Our range of galvanised tubeclamps™ fittings are used primarily to make handrail, guardrail and all types of safety railings but there are many other applications for tubular fittings including display systems, storage racks and retail displays. Our 119 two socket cross is used on straight and level guardrails to connect the mid rails to the upright. The upright in guardrails must remain continuous with the cross rails being cut. It is used in conjunction with the 104 fitting. Our 113 plastic end cap is used to seal the end of open tubes. This fitting is a frictional fit only for a permanent fix a suitable adhesive should be used.
