The 5015 Rolling Security Grille curtain is built for the long haul. The curtain consists of solid rods that are spaced 33% closer than standard security grille curtain construction. In addition, the links are 50% heavier with tube spacers on every rod, instead of every 10th rod. These metal gate upgrades make the curtain more secure and more durable than standard overhead grille construction.

The 5015 provides robust security without blocking vision or airflow. As an added aesthetic benefit, the steel gate construction allows for powder coating on the curtain.

Like all of our rolling grille products, the 5015 curtain stores in an overhead coil that is totally supported by extensions of the side guides. This means there is no need for any additional support beams at the security grille hood.

There are times when you need to balance security, visibility and air flow. The 5015 heavy duty security grille provides an enhanced level of security from standard grilles but retains the visibility and air flow so often needed in applications such as parking garages and store fronts.

There are times when you need to balance security, visibility, and air flow. The 5015 provides an enhanced level of security from standard grilles but retains the visibility and air flow so often needed in applications such as parking garages and store fronts.

The tube spacers placed on every rod not only ensure the utmost security and durability, they also allow for the 5015 grille curtain to be powder coated - improving aesthetics while maintaining the grille's rugged security.

The grilles are constructed for daily use and can withstand operation of up to 20 cycles per day – that’s 50K cycles for the lifetime of the grille. Dependent on curtain configuration and spring selection.

This grille is also available in 100K, high cycle construction for more than 20 cycles per day.

If your requirements call for increased speed (up to 24 inches per second), more than 50 cycles per day, or 300,000 cycles lifetime, consider our line of High Performance products.
