Security Grilles and Counter Doors

Name: Allura rolling shutter
Brand: Overhead Door

Rolling grilles and counter shutters for storefronts, pharmacies, cafeterias, and concessions.

From Century Avenue, our crews install and service security grilles and counter doors across 11 Maryland counties. A rolling or side-folding grille secures a storefront, corridor, or parking entrance without hiding it. It keeps air moving, light shining in, and lines of sight open. A counter door closes smaller openings, like pharmacy windows, cafeteria lines, ticket counters, and concession stands. This page covers the complete Overhead Door line: the 670, 671, 671S, 674, and 676 upward-coiling grilles, the side-folding grilles, the 650 to 665 counter doors, and the Allura 653 shutter.

Overhead Door Corporation warrants the 650, 651, and 652 counter doors for 24 months on all parts and components from installation, excluding labor. The Allura 653 shutter is covered for 24 months, with labor included for the first year. The EverServe 671S grille carries a 24-month or 300,000-cycle warranty with one year of labor. No warranty sheet in the document library covers the 670, 671, 674, and 676 grilles, the side-folding grilles, or the 655, 657, 658, and 665 counter doors. Their current brochures state a 12-month limited warranty on the upward-coiling grilles, 24 months on the side-folding grilles and 676 door components, and an OEM limited warranty on the integral frame and wood counter doors.

Upward-coiling security grilles

Models 670 and 671

Models 670 and 671 are the standard upward-coiling security grilles. They offer an attractive, functional way to secure retail, industrial, and commercial buildings without blocking air, light, or sight lines. They can be installed inside or out. The 670 curtain is mill-finish aluminum with an extruded aluminum bottom bar. The 671 is galvanized steel with a double angle steel bottom bar. Stainless steel in No. 4 satin or No. 2B mill is optional. Both coil a horizontal bar curtain in a straight lattice, with rods on 2 in or 1 1/2 in centers and links every 3, 6, or 9 in. Staggered brick or fire-retardant polycarbonate panels are optional. The counterbalance uses oil-tempered 20,000 cycle torsion springs. Push-up is standard, with chain hoist, awning crank, or electric operator optional. A slide bolt secures manual and crank grilles, while a chain lock secures hoists. An operator with automatic emergency egress meets IBC and NFPA 101 standards for hospitals, schools, offices, and libraries. PowderGuard Premium finishes come in about 200 colors. This is the grille our crews fit most often at mall storefronts and pharmacies around Baltimore.

Options include a brick pattern, aluminum or stainless steel links, and PowderGuard Premium. It runs in three-angle structural steel guides with UHMW wear strips. There is no counterbalance spring to break or retension. A directly driven roll on greaseable sealed bearings turns on an integrated gear, motor, and brake assembly.

Side-folding full closure grilles

Models 677 and 678

Models 677 and 678 are side-folding full closure grilles. They stack tighter than any other grille corporate offers. They provide a secure barrier against theft and debris for malls, airports, and concourses. Both fold on a truss-like frame made of 1/8 in clear anodized aluminum top and bottom plates. The 677 uses 1/8 in self-extinguishing polycarbonate for a nonbreakable view. The 678 uses 1/8 in tempered glass for a crystal-clear view. The 675 perforated panel for full ventilation and the 679 solid aluminum panel for maximum security complete the family. The curtain rides on a 1 1/8 in trolley inside a top-mounted aluminum track (1 5/8 in high by 1 3/8 in wide). It navigates 90, 120, 135, or 150-degree curves on a 14 in radius (22 in for wide body panels). Width is unlimited. Height runs up to 14 ft, or 12 ft on the 678. Operation is manual. It features a concealed cylinder hook lock at the lead post, shoot bolts at intermediate posts no more than 10 ft apart, and a trailing post that self-locks into a steel V-stop. Our estimators always walk the track run, curves, and pocket before quoting a side-folding grille.

They fold to about 2 in per linear foot on standard body panels, and 1 1/2 in on wide body panels, fitting into a pocket as narrow as 8 in. The 681 features a straight or brick pattern of 1/2 in aluminum tubes over three vertical rods on 1 in aluminum plates every 12 in.

They offer 1 in of vertical adjustment and use the same 14 in radius curves, posts, and locks as the full closure grilles.
