CURTAIN
E-Series™ Grille X – Roll down security door consists of the Alpine 6″ or 9″ straight pattern with aluminum vertical links. Continuous solid 5/16” hot dipped galvanized horizontal rods spaced 2” o.c. Continuous end links are made to prevent the curtain from leaving the side of the guides. The bottom bar consists of an extruded aluminum “T” bottom bar. 

E-Series™ Grille – Roll down security door consists of the Alpine 6″ brick or 9″ straight pattern with aluminum vertical links and horizontal PVC sleeves. There is a choice of 4 standard colors: bronze, black, silver, or gold. Continuous solid 5/16” hot dipped galvanized horizontal rods spaced 2” o.c. are to be covered with tubular spacers. Continuous end links are made to prevent the curtain from leaving the side of the guides. The bottom bar consists of an extruded aluminum “T” bottom bar. 

BRACKET PLATES
The carrying pipe counterbalancing shafts are made of steel plating no less than 1/4” thick. The drive end bracket plate is fitted with a sealed ball bearing and the bracket plates are mounted to the wall mounting angles with 1/2” fasteners. 

GUIDES
Produced from roll formed steel with return retainers to prevent the grille from leaving the guide rails. The mounting angles are a minimum of 2 1/2” x 2 1/2” x 3/16” angles. (Option: 3” mounting tube for up to a 20’ wide door and 4” mounting tube for a door over 20’1” wide. See Mall Dawn for mounting to tube configurations.) 

SPRING COUNTERBALANCE
To be housed in a steel pipe with a diameter and wall thickness to restrict maximum deflection to 0.03” per foot of door width. Hot rolled A36 material. Springs are of the helical torsion type which are designed to include an overload factor of 25% for optimum ease of operation. The springs are grease packed and mounted on a cold rolled steel inner shaft. Spring tension is adjustable from the outside of the end bracket plate. Sealed ball bearings prevent wear on the pipe shaft. Life cycles from 10M to 400M. 

HOOD Hexagon (OPTION: Square or Round)
Produced in 22 ga. steel and formed to fit the contour of the brackets with 3/8” thick intermediate supports used as needed to prevent excessive sag. 

Push-up, hand chain, hand-crank, or motor operation available.
