SDC 1490 / 2490 Series Narrow Right Angle Electric Bolt Locks
Concealed Electric Bolt Locks for Narrow Door Frames and Stiles
The SDC 1490AI and 2490AH Series Spacesaver® Narrow Right Angle Electric Bolt Locks provide reliable, concealed electric locking for commercial, institutional, and industrial access control applications where installation space is limited. Designed and patented by SDC, these narrow-profile electric bolt locks are specifically engineered to fit within 1-1/2-inch narrow door frames or door stiles, making them an ideal solution for applications where standard electric bolt locks may not fit.
Featuring a concealed mortise design, the Spacesaver® right-angle locking mechanism allows the stainless steel bolt to project perpendicular to the lock body. This innovative configuration enables installation with a simple mortise cutout in narrow frames or door stiles, delivering enhanced security without compromising the appearance of the opening.
Narrow-Profile Design for Concealed Security
The SDC 1490 / 2490 Series is designed to provide dependable electric locking in narrow-stile applications. By concealing the locking mechanism within the frame or door, these locks maintain a clean architectural appearance while reducing exposure to tampering and physical damage.
The stainless steel bolt rotates freely, making attempts to cut or tamper with the locking bolt more difficult. A specification-grade solenoid provides dependable operation and long-term performance, making the 1490 / 2490 Series suitable for demanding access control environments.
Automatic Relocking for Swinging and Sliding Doors
An integrated automatic relock ball switch keeps the bolt retracted while the door is open. When the door closes, it depresses the ball switch, automatically causing the bolt to project and secure the opening.
The ball switch is field adjustable to accommodate varying door gaps and features bidirectional operation, allowing the lock to be used with both swinging and sliding doors.
Available Models

1490AI – Narrow Right Angle Electric Bolt Lock, Failsafe
-
2490AH – Narrow Right Angle Electric Bolt Lock, Failsecure
The 1490AI is designed to unlock when electrical power is removed, while the 2490AH remains locked when power is removed. Select the appropriate configuration based on your access control system and door security requirements.
