🔹 SCRIBE-MASTER – DGJIG

Drainer Groove Routing Jig for Timber & Compact Laminate (With Flex-Tech)

The SCRIBE-MASTER DGJIG is a precision routing jig designed for cutting clean, consistent drainer grooves in solid timber and compact laminate worktops. Engineered for professional kitchen installers and fabricators, it delivers repeatable accuracy while maintaining a built-in 0.5° fall for effective water runoff.

Manufactured from CNC-machined Compact Grade HPL and incorporating Flex-Tech anti-bow technology, the DGJIG ensures stable routing performance — even when using heavier ½” plunge routers.

What the DGJIG Does

Routes drainer grooves in solid timber
Cuts grooves in compact laminate worktops
Maintains a 0.5° fall for water drainage
Produces 8 evenly spaced grooves at 50mm pitch
Supports consistent, professional sink installations

Ideal for Belfast, farmhouse and undermount sink installations.

Flex-Tech Stability System

When routing with heavier ½” routers, jig rails can flex or bow, leading to inconsistent groove depth or wavy cuts.

The DGJIG incorporates Flex-Tech adjustable support grub screws placed strategically along the rails to:

Prevent deflection
Improve groove consistency
Maintain cutter stability
Deliver uniform groove depth

This results in cleaner finishes and reduced rework.

Flex-Tech Stability System

Flex-Tech is Scribe-Master’s integrated anti-deflection support system, engineered to prevent rail bowing when routing with heavier ½″ plunge routers.

Adjustable support screws reinforce the jig directly beneath the router path to maintain:

• Consistent groove depth

• Cleaner surface finish

• Reduced vibration

• Improved routing accuracy

By stabilising the rail under load, Flex-Tech ensures precise, repeatable results — even on large format worktops and high-volume installations.

Built into all Scribe-Master draining groove jigs.
