Your New Leigh RTJ400 Router Table Dovetail Jig for
Through Dovetails, Half-Blind Dovetails and Box Joints
The RTJ400 was designed for the ever increasing use of router
tables in shops everywhere. The RTJ400 can produce sizes and
types of joints not possible with typical template jigs, including
through dovetails, half-blind dovetails and box joints (finger
joints), and thanks to the patented Leigh eBush, perfect fitting
joints are guaranteed every time.

Important! Inches and Millimeters
Text and illustrations in this English language user guide indicate
dimensions in both inches and millimeters, where applicable, with
“inches” first, followed by “millimeters” in square brackets, i.e.
1⁄2" x 2"[12mm x 50mm].
Do not be concerned that the inch/millimeter equivalents are
not mathematically “correct”. Just use the dimensions that
apply to your guides and bits.
The RTJ400 is covered by the following patent: U.S. Patent No. 8,534,329
Patents for all Leigh elliptical guide bushings: U.S. 8,256,475 UK GB2443974
IMPORTANT Jig Design Update
The drawings in this user guide show an earlier version of the jig
handles A. The handles now have two protrusions to protect the
