Ilco 7160DC Dummy Mortise Cylinder - 1" Length

The Ilco 7160DC Dummy Mortise Cylinder is a professional-grade architectural hardware component designed for doors that require a uniform appearance without functional locking capabilities. Engineered as a high-durability security and aesthetic solution, this 1-inch dummy cylinder is commonly used on the inactive leaf of a pair of doors to match the keyed cylinder on the active side. By filling the mortise prep with a solid brass housing, it provides a finished, tamper-resistant look while maintaining the structural integrity of the door's hardware schedule.

Constructed from solid brass, the Ilco 7160DC is built to withstand the rigors of commercial and institutional environments. Because it contains no internal pins or keyway, it serves as a permanent maintenance-free solution for decorative or non-functioning door preps. This cylinder is an essential component for architects and facility managers who prioritize a consistent, professional appearance across complex door openings in hospitals, office buildings, and retail storefronts.

Dummy Cylinder Function & Architectural Summary

The Dummy Mortise Function (non-functional) serves a critical role in both the security and the visual balance of a commercial entryway.

• Aesthetic Consistency: On a pair of double doors, the 7160DC ensures that both doors appear identical from the exterior. This prevents the "unfinished" look of an empty cylinder hole or a mismatched cover plate.
• Tamper-Resistant Filling: By filling the mortise prep with a solid brass unit, you prevent unauthorized individuals from using the cylinder hole as a point of leverage to pry or manipulate the internal lock case.
• Non-Operational Design: Since there is no internal plug or cam, the dummy cylinder cannot be rotated. It is purely stationary, making it the ideal solution for exit-only doors or inactive leaves where a key should never be used.
• Flexible Sizing: At a 1" length, this cylinder is perfectly sized for standard 1-3/4" commercial doors, ensuring a flush or near-flush fit with the escutcheon or rose trim.

Engineered Solutions for Facility Infrastructure

The Ilco 7160DC provides a strategic solution for common commercial doorway challenges:

• Eliminate Hardware Confusion: In large facilities, having a keyway on a door that is not meant to be opened can lead to broken keys and frustrated staff. The Dummy Cylinder signals clearly that the door is non-operable, preventing unnecessary wear on maintenance staff and the hardware itself.
• Weather and Debris Protection: An open mortise prep can collect dust, moisture, and pests, which eventually damage the internal mortise lock body. The 7106DC seals this opening, acting as a protective barrier for the sensitive internal mechanics of the door.
• Cost-Effective Design Symmetry: Rather than purchasing an expensive keyed-alike cylinder for a non-functional side of a door, the Ilco Dummy Cylinder provides the same architectural look at a fraction of the cost, making it a "value-engineered" solution for large projects.
• Corrosion-Resistant Performance: The solid brass construction ensures that the cylinder will not rust or seize over time, even on exterior-facing doors exposed to humidity or salt air.
  
• Simplified Retrofit Capability: Because it uses the standard 1.150" x 32 UNS threading, this dummy cylinder can be screwed into any standard mortise lock body or exit device in seconds, requiring no special tools beyond a standard mortise wrench.
