Amazon.com Product Description
If you’re tired of crawling under your router table to make adjustments, then you’re going to love the Bench Dog 40-016 ProLift Max Router System. This cleverly designed device allows you to make all height adjustments and bit changes from above, while standing comfortably at the router table. The system is particularly useful when working with large, heavy fixed-base routers.
The 40-016 has a precision-crafted cast-iron housing and durable bronze bushings that glide up and down on dual hardened-steel columns. The insert plate has three bit-hole sizes (2-inch, 2.6-inch, and 3.7-inch) for accommodating most router bits. A crank-style wrench is included for quickly raising and lowering the router from above.
All these exclusive features and heavy-duty construction don’t come cheap, but the Bench Dog 40-016 ProLift Max Router System is ruggedly built and designed to last a lifetime, even in a professional woodworking shop. Note that an adapter is required—and sold separately—for mounting routers measuring less than 4.2-inches in diameter. -- Joseph Truini
From the Manufacturer
ProLift Ni is Bench Dog's new cast iron top-adjust router system for fixed base routers! ProLift gives you the easiest bit changes on the market and the ability to zero-out and accurately set your bit height. The heavy duty ProLift Ni's core is a cast-iron motor housing, finned for cooling, with bronze bushings that adjust up and down on two hardened steel columns, guided by an 8 t.p.i. acme threaded shaft. This core is anchored to a 3/8-inch thick, cast iron, hard chrome plate that accepts three supplied steel insert rings (2-, 2.625- and 3.75-inch i.d.) and one supplied threaded insert pin. The insert pin mounts at four locations for freehand work. ProLift Ni is designed to accommodate for the largest routers, such as the Porter Cable 7518 (4.2 inches in diameter) and is built to last a lifetime. A speed wrench is included. An adapter is required to accommodate fixed base router motors with a diameter of less than 4.2-inch. Adapter sold separately. (See A1001 and A1002). Made in the USA.
