Protex Introduces Its Highest Strength over Centre Latch to Date



Big Bertha' Provides Three Times the Grip of Previous Strongest Product

24th June 2009: Redditch-based Protex Fasteners Ltd, manufacturer of the world's largest stock range of over-centre catches, has introduced the 490-9000 MSZN, its highest performance latch to date.

Codenamed 'Big Bertha', the new fastener and dedicated catchplate (Part No: 04-9000 MSZN) 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 7500 kgf and provides up to 30 mm grip range adjustment. At maximum capacity, it measures 85 mm wide, 40 mm high and 392 mm 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."
