The new Multi-Fence from HTC Products includes a unique feature: With the turn of a knob, the location of the fence can be moved left or right as little as a few thousandths of an inch.

The Multi-Fence is designed to replace the fence on the current models of the Biesemeyer, Jet Exacta, and Powermatic Accu-Fence. If you don’t have one of these three fences, you can buy a complete Multi-Fence system that includes the rails.

The Multi-Fence is available in both a contractor and a commercial version. I tried the commercial model, a well-made, heavy-duty product.

Both sides of the fence have smooth, durable plastic faces that can be replaced easily. And you can buy a kit from HTC that includes all of the hardware needed for an auxiliary fence, should you want to add one.

The micro-adjustment mechanism adds a couple of steps to the process of adjusting a fence, and the mechanism tended to stick a bit, making the fence jump slightly as I turned the know. As a result, the micro-adjustment feature looked to be only a marginal improvement over the random inaccuracies of a knuckle rap.

The cursor includes a magnifying lens to better view the scale, but the lines on the scale are too wide, and the cursor is located in the lens about 1/4 in. above the scale. At that distance, it was difficult to align the cursor and a line on the scale unless they were viewed from directly above. Should you shift your head even slightly, the reading on the scale could easily change by 1/64 in.

The Multi-Fence was most useful for shaving a hair’s width from a tenon and for trimming a box lining to length so that it pressed perfectly into position.

If you have an older fence system, check with HTC to make sure the Multi-Fence will fit the rails. It barely fit those on my 25-year-old Biesemeyer fence system, and it wouldn’t fit at all on another saw with an older Biesemeyer clone.
