Many modern material
selections are non-magnetic and require alternative methods for securing the PRO 360 and
PRO 3600 Digital Protractors to those working surfaces, especially at non-level angles.
The Kell-Strom Vacuum Base
Attachment allows for use of the PRO 360 and PRO 3600 at virtually any angle on surfaces
capable of holding a vacuum.
The
Vacuum Base will 'stick' to aluminum, ceramic, composite, glass, plastic, finished wood,
metals and virtually any smooth or polished surface that can hold a vacuum.
The main body of the Kell-Strom
Vacuum Base Attachment is made from aircraft grade aluminum and is designed to accept and
be used in conjunction with any of the other attachments made for these protractors such
as the Laser Module and Universal Attitude Adapter. Stack up the attachments to get the
capabilities you need. (Vacuum Base is not to be used with Magnetic Base.)
