Learn step-by-step how to install a magnetic flap pet door in a metal frame, including measuring, cutting, and securing tips.

Quick Answer

Measure your pet's height and width, mark the door panel, cut carefully with a jigsaw, then mount the magnetic flap frame using the included screws.

Why a Metal Frame Changes the Installation

Installing a pet door into a metal frame is different from wood or drywall. Metal is harder to cut and requires the right tools to avoid bending the frame. You'll need a jigsaw with a metal-cutting blade and a drill with a metal bit for pilot holes.

A magnetic flap design helps the door seal tightly after your pet passes through, which is especially useful in a metal frame where gaps can let in drafts. The strong magnets also help the flap stay closed against wind.

Step-by-Step Installation Steps

  1. Measure your pet: Measure your pet's height from floor to shoulder and width at the chest. Add 2 inches to each measurement to determine the minimum opening size. Check that the pet door's opening is larger than your pet's measurements.
  2. Mark the cutout: Trace the provided template on the metal door at the desired height. Ensure the bottom of the opening is about 1-2 inches above the floor to allow easy stepping. Double-check the template is level before cutting.
  3. Drill pilot holes: Drill small pilot holes at the corners of the traced rectangle. This prevents the metal from bending and gives your jigsaw a starting point. Use a metal bit and go slow to avoid overheating.
  4. Cut the opening: Use a jigsaw with a fine-tooth metal blade to cut along the traced lines. Keep the saw steady and let the blade do the work. Wear safety glasses and file down sharp edges after cutting.
  5. Insert the pet door frame: Slide the magnetic flap frame into the opening from the exterior side. Ensure it sits flush against the metal surface. If the fit is too tight, gently file the edges rather than forcing it.
  6. Secure and test: Screw the frame into place using the provided screws, then test the flap by pushing it open. Make sure it swings freely and seals magnetically when closed. Check the screws are tight but not stripped, and verify the flap closes completely.
