The Interclamp® DDA Assist range has been especially designed for disability handrails to help compliance with AS 1428.1-2009, Design for Access and Mobility General Requirements for Access - New Building Work, the Building Code of Australia and other national standards requiring a smooth handrail. In order to give our customers more choice, a range of both internally expanding clamps and saddle type fittings is available, neither of which requires the use of welding, threading or specialist tools.
Our classic range of internally expanding fittings requires no riveting or drilling of tube, whereas the saddle-type fittings require less tube cutting and hence easier handrail alignment. No other special fittings are required, which enables full integration with both new Interclamp® systems and the refurbishment or upgrading of existing tubular structures to help meet the newer access specifications.
In order to meet the requirements of the above standards, the range forms flush joints with size C42 tube. Tube (and fittings where necessary) may be coated in AS or RAL colours to help meet contrasting colour requirements, including the SSA Industrial Safety Colour Code, AS 1318-1985. Steps and disabled access slopes may easily be accommodated, facilitating compliance with public access standards.
For C42 size internally expanding Assist fittings (as with type 150), tubes must be 42.4mm od x 3.2mm wall thickness eg. 1 1/4” medium weight to AS 1074-1989, Steel Tubes and Tubulars for Ordinary Service. All cut tube ends must be deburred and treated with Interclamp® Silver Galvanising Spray or other suitable protection. Optional O-rings may be fitted to each end of the expanding assist fittings to achieve the best finish.
