Protex introduces highest strength over centre latch

Protex introduces highest strength over centre latch
Redditch-based Protex Fasteners has introduced the 490-9000 MSZN, its highest performance latch to date. Codenamed 'Big Bertha', the new fastener and dedicated catchplate have been developed to meet the types of super heavy duty application found in earthmoving, mining equipment, aggregate conveyors, agricultural plant, freight and off-highway vehicles.

The zinc plated, mild steel latch assembly achieves an ultimate tensile strength (UTS) of 7500kgf and provides up to 30mm grip range adjustment. At maximum capacity, it measures 85mm wide, 40mm high and 392mm long, including catchplate. A sealing facility is also incorporated in the catchplate as standard, to provide additional security.

According to Protex's systems and development manager, Adrian Symons: "Big Bertha has been developed to meet customer requirements for reliable fastening under the most demanding operating conditions, including extremely high dynamic and vibrational loads. 

"It perfectly complements our existing fasteners for light, medium and heavy duty applications. But with around three times the ultimate tensile strength of our largest 40, 41 43, and 44 series catches, the new 490-9000 MSZN extends our products' capabilities into a completely new area of high strength fastening requirements."

Big Bertha joins Protex's extensive range of over-centre type fasteners, which includes more than 550 quick action versions produced in both stainless and mild steel.
