A Kee Klamp is a structural pipe fitting commonly used in the construction of handrails and barriers. Fabricated installations comprise the fittings and separate tubing components, which can be sized on site. The system was devised in 1934 and is made by a subsidiary of KIG Holdings. The fittings are mostly supplied to third parties for sale to fabricators, with a small proportion of sales being made internally to specialist divisions of the company.
