Magswitch Magsquare 165 #8100494
The Magsquare 165 produced by Magswitch (8100494) is the step up from the Magsquare 150. With a magnetic force of over 165 lbs. on all four sides and the bottom of the square, you will be able to hold metals up to 0.25 inches thick with ease--and not just flat metals. With a v-shaped groove at the bottom of this unit, it can be used on flat, angular, or even rounded metals.
The Magsquare 165 has M5*8 threaded holes on all sides of the unit to allow for the creation of your own fabricated jigs, and an on/off switch that allows you to easily place the magnets exactly where desired. Transportation and storage is also easier, with no worries about nuts and bolts in your toolbox hitching a ride on the powerful magnets and no damage to any sensitive electronics in the vicinity of the unit.
