Genuine Juki Lower Knife Holder (Part #131-49505). This authentic OEM mounting block is specifically engineered for the Juki MO-6714S Series, providing the stable foundation required for the lower blade during high-speed 4-thread overlocking.

Precision Trimming Foundation
The lower knife holder is a critical structural component that maintains the fixed position of the lower blade. The 131-49505 is manufactured to Juki’s exact micrometric tolerances, ensuring that the lower knife sits perfectly vertical and parallel to the needle path, allowing the upper knife to shear fabric with "scissors-like" precision.

Why Choose the Genuine 131-49505 Holder?
MO-6714S Specific Engineering: Designed to interface perfectly with the MO-6714S machine frame, ensuring all mounting holes and adjustment slots align without modification.

Vibration-Dampening Casting: Machined from high-density industrial alloy to absorb the harmonic vibrations of 7,000+ RPM operation, preventing "blade chatter."

Hardened Adjustment Surfaces: Features precision-milled channels that resist wear and scoring, allowing for smooth and accurate lateral adjustment of the cutting width.

Superior Thread Integrity: Crafted with hardened internal threads to prevent stripping during the frequent tightening and loosening required for knife height adjustments.
