Sargent 10-3049 Outside Rose Spring Assembly | 2003–2023 Series

The Sargent 10-3049 is a genuine OEM replacement spring assembly specifically engineered for the outside rose of Sargent locksets. If your exterior lever is drooping or fails to return to its horizontal position, the internal springs have likely succumbed to the stress of high-traffic use or environmental factors. Designed for locks manufactured between 2003 and 2023, this assembly restores the "factory-fresh" snap and alignment required for professional architectural hardware.

Precision Engineering & Performance Features

• Modern Series Compatibility: Tailored specifically for all Sargent locks and latches produced from 2003 through 2023, including the flagship 10-Line.
  
• Fixes Exterior Lever Sag: High-tension internal coils counteract the weight of the lever and any attached trim, ensuring the handle remains perfectly level and ADA-compliant.
• Grade 1 Architectural Durability: Manufactured by Sargent (Assa Abloy) to institutional standards, providing long-term reliability in schools, hospitals, and high-security office buildings.
• Seamless Professional Repair: Allows maintenance teams to restore a lock’s functionality without the expense of a full hardware replacement.
• Direct OEM Fit: Engineered to seat perfectly within the outside rose housing, eliminating mechanical "play" and vertical wobble.

The Sargent 10-3049 is a critical part for maintaining building security. A sagging outside lever is more than just an aesthetic flaw; it can cause internal friction that prevents the latch from fully deadlocking into the strike. If you are noticing sag on the outside, it is common for the inside spring to be worn as well.

Installation Note: For a permanent repair, ensure the lock is properly aligned within the door prep before tightening. The rose assembly must be clamped securely to the door leaf using high-strength thru bolts. If the thru bolts are loose or the door is hollow/damaged at the mounting points, the lever will shift during use, which causes the new spring assembly to wear unevenly and fail prematurely.
