Sargent 10-3048 Inside Rose Spring Assembly | 2003-2023 Series

The Sargent 10-3048 is a genuine OEM replacement spring assembly designed to restore the horizontal alignment and snap-back tension of your inside door levers. Engineered specifically for Sargent locksets manufactured between 2003 and 2023, this assembly is the definitive solution for "lever sag." When internal springs fatigue over millions of cycles, the lever begins to droop; installing the 10-3048 restores the crisp, responsive feel required for high-traffic architectural environments.

Precision Engineering & Compatibility

• Targeted Manufacturing Era: Specifically calibrated for all Sargent locks and latches produced from 2003 through 2023, ensuring 100% mechanical compatibility with modern 10-Line
  
• Eliminates Interior Lever Sag: High-tensile return springs provide the vertical lift necessary to keep the lever perfectly level, ensuring your facility remains ADA-compliant and aesthetically professional.
• Grade 1 Performance: Built by Sargent (Assa Abloy) to institutional standards, this assembly is designed to withstand the rigors of schools, hospitals, and busy office corridors.
• Cost-Efficient Maintenance: Avoid the unnecessary expense of a full lockset replacement by simply renewing the internal spring mechanism behind the inside rose.
• Seamless Installation: Designed as a direct drop-in replacement, allowing for a fast and effective repair of the interior trim.

The Sargent 10-3048 is an essential maintenance item for passing building inspections. A sagging lever is often a red flag for inspectors as it can indicate mechanical wear that might prevent the door from latching or unlatching properly during an emergency.

Installation Note: To ensure the longevity of your new spring assembly, check the alignment of the lockset during installation. The rose should be perfectly centered and clamped firmly to the door leaf using high-strength thru bolts. If the mounting is loose or the thru bolts are stripped, the lever will wobble, which puts uneven stress on the spring coils and leads to premature failure.
