DDA & RNRC range

The DDA & RNRC profiles comprise a Hardnose PVC-u channel and choice of slip-resistant inserts.

The profiles feature and extended insert design to provide additional slip-resistance around the leading edge of the stair edging (nosing). This ensures that foot contact is always made with the slip-resistant element of the stair edging.

Profiles are available with 55mm treads and 40mm or 55mm risers to meet the guidelines in Approved Document M of The Building Regulations 2000 and BS 8300-2:2018.
