Access Ports for Insulated Pipes
These flexible ports are often used to inspect insulated pipes and tanks for corrosion. Their frame has locking ridges to secure it in insulation that is at least 3/4" thick; no mounting screws or caulk needed. The panel fits snugly into the frame for a watertight seal. Panel opening is up to 1 1/4" smaller than the cutout.
Tank and Hopper Access Panels
Use these rectangular panels to access and inspect the interior of tanks and hoppers. All have gaskets to shut out dust and moisture. They also have a padlockable hasp that accepts up to a 5/16" dia. shackle. The panel opening is the same size as the cutout.

Weld-On Sights
Weld these sights to single-wall tanks. They’re often used to monitor contents in process vessels, mixers, and bulk containers.
316L stainless steel sights are more corrosion resistant than 304 stainless steel sights.
DIN 11851 rated sights meet dairy fitting standards.
Sights with a bolt-on window should be welded to a hole in your tank wall.
Sights with a screw-together window make it easier to access your tank and clean the window than sights with a bolt-on window. To install these sights, place the body in a hole on your tank wall and weld it. Then twist on the window and tighten with a spanner wrench.
