Weld-On Sights
With Bolt-On Window
With Easy-Access Window
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 easy-access windows allow quicker access than the bolt-on window. Unscrew the window from the body to clean the glass or access the tank.

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.
