The Exam Room Counter Door allows for the safe treatment of behavioral health patients in standard rooms saving healthcare providers money and resources while providing the needed security for patients.

The Model ERC20 Fire-Rated Integral Frame and Sill Counter Shutter takes a subtle, stylish approach to fire protection. Its design is defined by a streamlined profile and compact, stainless steel components. Factory-assembled with a frame, hood, and fascia, the unit is UL-Rated for up to 1 ½ hours and sets into existing walls for effortless installation. Where more compact door components are preferred, the shutters quickly and reliably close to the sill.

The 5015 Rolling Security Grille curtain is built for the long haul. The curtain consists of solid rods that are spaced closer together compared to a standard security grille’s 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.

Businesses with service windows or open counters are at risk of intrusion, vandalism, or theft when the staff leaves for the day. To protect your merchandise and equipment, invest in a durable counter door that blocks entry, obscures vision, and provides an insulating seal.

Commonly utilized in cafeterias, concession stands and ticket booths, our Rolling Counter Doors provide accessibility and security in interior and exterior finished wall openings. These doors are manufactured with smaller, more aesthetically pleasing door components – such as the guides, slats, brackets and hood – than traditional rolling doors, so they require minimal headroom and can be custom-fit into a wide variety of openings.

Need to securely separate two spaces but still need airflow and visibility? Our Rolling Security Grilles are your answer. Our durable Rolling Security Grilles keep areas off-limits, require little to no maintenance and can be configured to meet your desired aesthetic.

Roll-up service doors provide security against entry as well as protection from weather at exterior and interior openings in industrial, commercial, institutional and other buildings. These service doors are made from slats of formed galvanized steel, aluminum or stainless steel that roll up to store in a coil above an opening.

Cookson SteelWeave mesh security grilles provide reliable protection against theft and intrusion while adding to a building’s architecture. These security grilles and mesh counter doors feature durable stainless steel and are suited for use indoors or outside facing the elements.
