DDA Range

DDA Range – Handrails for disabled access

Dda small fisher alvin key clamps & tubes
An example of our DDA handrail

Under the terms of the Equality Act 2010 (previously the Disability Discrimination Act), reasonable adjustments need to be made to public and commercial buildings to overcome physical barriers which prevent disabled access. The Building Regulations recommend an outside diameter tube size for installations of between 40mm-45mm.

Our DDA range offering DDA Ramps has been designed to meet these requirements by providing a non-discriminatory handrail solution that complies with the Equality Act and Part ‘M’ of the Building Regulations. The range allows the construction of a smooth continuous handrail of 42.4mm diameter.

Tube Clamps – DDA Range For Disabled Access

DDA key clamp handrails are supplied Hot Dip Galvanised as standard but can be supplied in a powder-coated finish to RAL standard colours (subject to quantity and availability). In cold temperatures, a powder-coated finish will give the impression of being warmer to the touch.

Due to the continuous nature of the DDA Access handrail, the visually impaired would be able to follow the handrail in its entirety without risk or harm being caused by any intermediate upright posts.
