The system of interchangeable feet for security barriers uses two interchangeable parts (1) which are bolted on to the plate (2). The plate, in turn, is soldered to the barrier (3). The two parts are interchangeable and identical, and replacement parts can be used on either side. The feet are bolted on in an opposed way so that tightening occurs by action-reaction. USE/ADVANTAGE - For safety barriers used to contain or guide people or animals. Feet easy to attach. Ease of maintenance, easier to stock. No need to solder galvanised parts.
