With the help of a fellow woodworker, I've found the OEM source for the most incredible vacuum sealing tape available. This is not a knock-off. This is a high density on-board gasketing tape comparable to high-end industrial vacuum clamping systems from ShopBot, C.R. Onsrud and Holtzer.

The tape is coated on one side with an acrylic pressure sensitive adhesive. The foam's 1/8" (0.125") thickness assures conformability to a wide range of substrates and its 3/8" width allows a tighter radius for small parts from the substrate on your CNC router or vacuum clamping/templating jig.

What Is it Used For?
Vacuum clamping is the easiest to way to hold an object for routing and sanding. Vacuum clamps powered by a venturi or electric pump can generate up to 1700 lbs per square foot of clamping pressure without marring the work piece. If you're unfamiliar with vacuum tape, this is the stuff that makes the air tight seal between a vacuum jig and the work piece.

About the Pricing...
From the equipment manufacturers, you could expect to pay $28 to $40 per roll. Why is it so expensive? Simple. This is the only vacuum tape designed exclusively for vacuum clamping and templating. This series of vacuum tape does not allow shifting or creeping of the work-piece. As I've said many times on other products available on my website, I've bought a huge quantity of this tape to get the absolute best price.

Features

• Closed cell foam gives this tape greater abrasion resistance.
• The self-stick adhesive system allows the gasketing to be easily applied to virtually any sound jig material.
• Eliminates creep and chatter which makes sanding operations faster and routing operations more accurate.
• This tape offers the lowest compression set of any tape available (this means that it will return to its original size after each clamping operation).
• Can be used with small and tight radii on the vacuum jig.
