Sternfenster partner with Yale to boost bi-fold security

Trade fabricator Sternfenster, has strengthened its partnership with Yale Door and Window Solutions after choosing to supply the Yale Lockmaster multi-point lock for use across its aluminium bi-fold door offering.

Mike Parczuk, Managing Director for Sternfenster, said: “We have been using a range of Yale products, including locks and friction stays, for a number of years and have faith in the brand and quality of products.

“As the bi-fold door market is booming, we’re dedicated to developing our existing range and as such have chosen to offer the Yale Lockmaster due to its superior security credentials.”

The Yale Lockmaster 28mm backset multi-point lock features a combination of hooks and anti-lift bolts for greater security, along with smooth operation, tolerance and ease of use. The lock is available in standard 16mm euro groove and u-channel variants to suit various aluminium systems. What’s more, all of the Lockmaster® range is manufactured in the UK and carries the Made in Britain marque.

Paul Atkinson, Sales and Commercial Director for Yale Door and Window Solutions, said: “We have a great working relationship with the team at Sternfenster and by taking on the Lockmaster multi-point lock they can promote a high security bi-fold package that fits the slim style aluminium look that is popular today. This comes with the added benefit of the Yale guarantee”

Sternfenster is committed to enhancing its security credentials and following the updated PAS 24:2016 standard has also moved onto the Yale Postmaster Professional Letterplate, further demonstrating its promise to provide its installers with superior solutions.
