Heavy Duty Mount System

The Havis Heavy Duty Mount is a rugged, professional grade computer 

mount that combines the perfect balance of strength, safety, and ultra-

smooth operation worthy of your most mission critical computer devices.

Heavy Duty Mounts are stout: Heavy gauge steel poles, welded, rigid seat bases along 

with its universal support arms virtually eliminate wobble and vibration that can make 

reading difficult.
Heavy Duty Mounts are safe: A standard stop collar allows the installer to adjust 

the height and limit the computer from telescoping below desired height. Order the 

optional top lock and the entire rotation can be positively locked in place to prevent the 

unit from spinning in a collision or air bag deployment.

 

Heavy Duty Mounts are smooth. Designed with a unique precision machined aluminum 

clamp and lever along with a PVC split sleeve for no metal-to-metal contact when 

adjusting the pole. All moving parts have a glossy, ultra smooth e-coat finish which 

further reduces 

friction. Order the optional “lift assist” gas shock kit that you can drop in 

the pole assembly and the Heavy Duty Mount will help you do the lifting and prevents the 

heavy equipment from slamming down.
