"Inspection Hatch" Catalog

"Inspection Hatch" Catalog

You can select the appropriate inspection opening from a rich lineup!

The "Inspection Hatch" catalog features a rich lineup of suitable types that can be selected based on the usage location and budget. In fact, it is a waste to arbitrarily decide on a uniform inspection hatch. Opportunities to install inspection hatches are increasing due to the promotion of performance display systems. Indoor inspection hatches should be as inconspicuous as possible. However, for example, an inspection hatch inside a closet may not need to be as hidden. This catalog allows you to choose based on aesthetic sense and budget. We also introduce our original products, including easy-to-inspect magnetic types. [Featured Products] ■ Smart III Inspection Hatch ■ Sound-absorbing Inspection Hatch ■ MJK Magnetic Inspection Hatch ■ Non-frame Hatch ■ Inspection Hatch with Lid ■ Frameless Inspection Hatch, etc. *For more details, please refer to the PDF document or feel free to contact us.
