DNSB-BM Wall Tie/Sway Brace

This DNSB-BM is our most popular acoustic sway brace. It is a low frequency wall tie. You have a choice of a bolt end for stud walls or hooked end for masonry walls.

The DNSB-BM sway brace is available in two different sizes. The standard brace requires a minimum cavity width of 76mm and is suitable for cavities up to 140mm wide. For larger wall cavities, the central hook end bolt is replaced with a longer hooked bolt to meet the required cavity width. Our acoustic wall ties are supplied pre-compressed to ensure consistent acoustic isolation while tolerating a range of wall loads.

If you would like to order or learn more about this product please contact Mason UK’s acoustic engineers.
