Aluminum Security Grille with Heavy Duty Bars (Mandrel Construction, Sleeve)
The 51350 series minimum security grilles feature heavy duty aluminum bars fixed at 0º with an extruded aluminum frame. This design allows for a secure area in a humid environment without the confining appearance of other security grilles.
