# Custom Door Operator Enclosures

https://kdisplay.com/products/door-access-systems/door-operator-enclosures

K-Display, a Chicago sheet metal fabricator, makes door operator housings, service covers, control boxes, and mounting plates from your operator and component drawings. Parts ship bare, powder coated, or assembled with studs, nuts, and latches installed.

## Overview
We build door operator enclosures as the metalwork on a sliding door operator: housings and shrouds around the motor and drive, service covers, control boxes, and the mounting plates that carry the components inside. Parts are laser cut and formed from aluminum, carbon steel, galvanized steel, galvanneal, or stainless steel, and leave bare, powder coated, or assembled with studs, nuts, and latches installed. Control cabinets and pedestals that stand at the opening are gate & access-control enclosures.

## Process
- Laser cut: We laser cut the body, cover, and plate flat, with the keyholes, slots, and cable holes in place.
- Form and install hardware: We form the flanges and cover overlap, then install studs, nuts, and latches in the bare parts.
- Mask, coat, and assemble: We mask the threads and the surfaces you mark bare, powder coat, and assemble the cover and plate on the body.

## Typical parts
- Operator housings: Formed shells and shrouds around the motor and drive, with openings for the drive and cables.
- Control boxes: Bodies and covers with slotted flanges, keyhole slots, and cable holes, mounted on the operator.
- Removable covers: Service covers with the overlap and fastener holes that let them lift off.
- Mounting plates: Flat plates that carry the components inside the housing, with a hole pattern for each.

## Design considerations
- Drive clearance: The motor, shaft, and drive set the inside envelope. A wall or flange in that space rubs the drive.
- Cover removal: A service cover has to lift off past the wall beside it. A catching overlap or fastener head leaves the operator unreachable in place.
- Cable entries and the NEMA type: Every cable hole is a gap in the enclosure. The NEMA type you name sets the closure and entry hardware, and a hole that misses that hardware's size leaves the gap open.
- Threads and bare surfaces: Powder film insulates and fills threads. A coated contact surface stops conducting, and a coated thread stops turning.
