The ProLinea twin cam espag window locking system, manufactured from high grade steel and zinc alloy, offers enhanced window security. During operation paired locking points - mushroom headed steel cams - travel 20mm towards each other, in a vice-like grip. Each pair locks into their striker to provide strong, secure, anti-jemmy protection.

Designed in-house the robust reverse action gearbox features unique, concealed twin pinion technology to ensure smooth operation and durability. Additionally, the compact gearbox has been designed to require minimal routing to ease fabrication. Backset sizes are clearly marked on the gearbox, 20mm or 22mm, for quick identification. To further speed fabrication espags are preset in the open position and a handing identification window on the gearbox clearly displays LH or RH.

Suitable for both side hung and top hung applications and both standard and reduced depth eurogrooves, this high security espag is available in a range of lengths, in 20mm and 22mm backsets, and with either 8mm or 9mm adjustable mushroom cams to suit a range of PVCu profile systems as well as timber and aluminium.

The ProLinea twin cam espag has been successfully tested at the UKAS accredited Mila Test Centre to the enhanced security performance requirements of BS 7950, has achieved 50,000 cycles - more than twice the standard requirement - to ensure operational reliability, 240 hours salt spray to ensure weather resistance and meets the enhanced security requirements of Secured by Design.

Strikers are also available.
