What buyers need to know first
Hardware buyers usually compare door type, opening size, fire rating, finish and access-control compatibility before asking for price.
Triangle Housing Style
The E183 page shows a triangle door closer appearance for buyers who want a different housing shape from the hexagonal or round closer bodies.
Door Weight Range
The catalog positions TO-E183 for 800-1000mm door widths and 45-65kg door weights, giving it a slightly higher weight range than TO-183 / C183.
Non-Hold-Open Selection
The technical table lists non-hold-open only, so this page is useful when the project does not require a hold-open function.
