How Do I Select and Measure a Bottom Hinged Intake Door?


First, determine what type of handle is on the intake door. Examples of handles are: pull handle with thumb latch trigger, T-style handle, lever style handle, palm button, electrical interlock push button with handle, or foot pedal.

Second, determine if your chute intake door has the closer exposed or enclosed in a mechanism box. If your chute intake door has a mechanism box the doors you will want to begin looking at will be in our "W" or "WM" Series. If the closer is exposed, any of our other Series doors will apply.

Third, determine if your chute intake door has electrical interlocking or pneumatic functions and make sure to determine the door you are ordering is compatible. Most electrical interlocking systems are 120 volt or 24 volt. The 120 volt systems will usually have 5-wire or 7-wire systems. At this time, pneumatic chute intake doors and systems are available only by calling or emailing the office.

Fourth, determine the size of your chute intake door. The size of a chute intake door is basically the size of the opening. To see what size replacement doors you need, open the existing doors and measure the openings. The width is always indicated first, so a 15" x 18" door would have an opening 15 inches wide and 18 inches high, rounded to the nearest inch.

Chute intake doors should have the name of the manufacturer on them. This information is helpful in determining what type of replacement door your system requires. Using our extensive, archival database we can determine the perfect replacement door compatible with your existing system.
