Extra-Large Opening

The extra-wide opening measures 16" wide x 14 ¾" high and exceeds others in the industry (competitor models are up to only 5" x 2").

Ballistics

The gun port meets the ballistic standard of UL 752 and is available in Levels 1 to 8.

Less Friction, Long Lasting

The sliding gun port features a delrin insert in the sliding mechanism to minimize friction, reducing wear and tear and ensuring long-lasting performance.

Bullet-Resistant Louver

Krieger's bullet-resistant louvered vents allow air to pass through the door while providing a high level of security and protection.

Meets Ballistic Standards

Vents are ballistic resistant up to UL 752 Level 8 (other ballistic ratings available upon request). The louvered steel construction resists multiple impacts from 7.62mm NATO ammunition with no penetration or spalling.

Custom Configurations

Louvered vents are available in a wide range of sizes and configurations, including hybridization options with door assemblies.

Louver-Free Area

The louver-free area percentage is calculated at 12–17% depending on size and configuration of the armored blades.

High-Security Day Gate

Krieger’s day gate provides superior security, access control, and visual clarity where controlled substances, weapons, equipment, and other sensitive materials are stored.

Carbon Steel Construction

Krieger’s high-security day gate is constructed from hot-rolled carbon steel tubing and 9-gauge expanded metal. It features ¾" flattened diamond-shaped openings with an impressive 64% open area for visual clarity.

Multiple Performance Options

Depending on the level of security desired, the day gate can be paired with a flush security door, providing multiple performance options.

Accessories

All of Krieger's day gates can be equipped with integral access panels or pass-through features as needed.
