NBS Handrail & Balustrade Specifications

To help specify the Laidlaw range of handrail and balustrade systems, the following specification paragraphs are provided in a format compatible with NBS. These are also available electronically on NBS Plus or by contacting the Laidlaw Handrail and Balustrade Enquiry Line on 01902 600420. They can be cut and pasted into an NBS specification.
