The MS859 handle lock is a mechanical panel lock designed for secure access control in industrial and commercial environments. Here’s a detailed overview of its specifications, dimensions, and applications:

Key Specifications

• ‌Model‌: MS859 series (variants: MS859-1T, MS859-1B, etc.)

• ‌Lock Core Type‌: Tumbler lock core (compatible with multiple key profiles)

• ‌Material‌: Zinc alloy base + PA66 handle, hardened steel shaft

• ‌Surface Treatment‌: Phosphating black phosphate base, bright white zinc plating on lock core

• ‌Performance‌: Handle pull force 105N, maximum static load 220N, maximum input torque 20N·m

• ‌Key Configuration‌: Standard K15 series key (customizable)

• ‌Lock Core Specification‌: S1845Y00005 (Ts=4)

Critical Dimensions

• ‌Overall Dimensions‌: Handle length ~112.5mm, lock body height ~43mm, mounting hole pitch (horizontal 36mm, vertical 25mm, per installation diagram)

• ‌Cutout Requirements‌: Panel cutout diameter Φ11.2mm, lock body installation hole diameter Φ10mm, retainer (accessory) hole diameter Φ5.2mm

• ‌Lock Bolt Options‌: Available in multiple types, including round tumbler lock (MS859-1-1), 8mm triangular bolt (MS859-1-2), 8mm square bolt (MS859-1-3), 7×9mm square bolt (MS859-1-4), inner square core (MS859-1-5),一字 core (MS859-1-7), and 7mm three-cornered bolt (MS859-1-8)

Applications & Compatible Equipment

• ‌Core Application Areas‌: Industrial control cabinets (distribution boxes, server cabinets, automation control cabinets), engineering machinery (cab doors, maintenance doors of excavators, cranes), commercial vehicles (cargo doors, toolboxes of box trucks, special-purpose vehicles)

• ‌Compatible Door Types‌: 5-20mm thick metal sheets (cold-rolled steel, aluminum alloy), requiring standard keyhole machining, supporting left/right door opening directions

Product Structure & Functional Features

• ‌Mechanical Transmission‌: Planar handle actuated tumbler lock core, 360° handle rotation, with anti-creep function

• ‌Accessories‌: Standard retainer (fixes lock body to door), optional lock bolt types (e.g., round, triangular, square)

• ‌Installation Flexibility‌: Multiple bolt types (e.g., MS859-1T01001 for round tumbler lock, MS859-1T04001 for 8mm triangular bolt) to match door lock requirements; installation hole pitch can be adjusted as needed

Selection & Usage Tips

• ‌Model Matching‌: Select based on bolt type (e.g., MS859-1-1 for round tumbler lock, MS859-1-8 for 7mm three-cornered bolt) to ensure compatibility with door keyholes

• ‌Environmental Suitability‌: Suitable for dry, moderate corrosion environments; humid or outdoor use recommends stainless steel upgrade

• ‌Installation Notes‌: Ensure lock body perpendicular to door to avoid bolt jamming; securely fix retainer to prevent loose lock performance

The MS859 handle lock combines mechanical reliability, multi-bolt adaptability, and high-strength materials, making it a common choice for industrial equipment lockout applications, especially in scenarios requiring high security and durability.
