3,000 hours and counting
November 2017

LOCK LOCK, the high security handle from Brisant Secure, has now spent over 3,000 hours in independent corrosion testing, without pitting or blistering, over 12 times the amount of salt spray testing required to achieve EN 1906:2012, and over six times over the maximum specification.

“Pitting on door furniture is one of the industry’s dirtiest secrets,” said CEO Nick Dutton.

“In fact, Lock Lock has spent longer in the salt spray chamber than some handles that I used to buy lasted on the door. Many manufacturers only offer a guarantee on performance, or a token one on the finish. Some recommend stainless steel for ‘coastal’ areas – but 63% of the UK population live less than 9.3 miles from the sea. And 36% live within just 3 miles. What might be fine for inland Europe, America or Australia, just isn’t suitable for an island like ours.”

Brisant has three Lock Lock handles in the testing chamber, in polished gold, chrome, and white powder coat. They’ve been sprayed with over 65kg of salt so far, and Brisant says not one of the finishes has shown any signs of corrosion. 

Brisant has now increased Lock Lock’s initial 2-year guarantee to 5 years, and will go further if the handles tested continue to perform.

Nick added: “Lock Lock took 24 months to develop. Each handle is coated twice with copper and then twice with nickel, and its designed with a seamless curve so there are no edges or corners, traditional weak spots for corrosion.”
