How to Assemble a Staple Gun
Heavy-duty guns drive staples deep into materials for extra fastening power. (heavy duty stapler image by Christopher Dodge from

Staple guns are available in many different models, depending on what you need to fasten. A light-duty staple gun is used mainly for connecting thin items. A heavy-duty staple gun will fasten thick materials like tar paper for roofing, housing underbellies and thick plastic sheeting. A heavy-duty staple gun has much longer staples to fasten items deep into wood and other materials. Assembling a staple gun is a fairly simple and straightforward task.

  1. 1

    Grasp the clip for the magazine unit between your thumb and forefinger with one hand while holding the staple gun with the other hand. The clip is at the back of the staple gun on the bottom. Pull the clip straight back and out from the staple gun to a stop position where it will remain in place.

  2. 2

    Expose the staple channel by turning the staple gun over so the bottom faces up.

  3. 3

    Insert a full strip of staples into the staple channel with the staple tips pointing down into the staple gun. The tips sit on each side of a metal rod that supports the staples.

  4. 4

    Grasp the clip for the magazine unit between your thumb and forefinger. Push the clip into the staple gun. The clip will load the staples and lock the magazine in place.

Tips and warnings

  • Replace staples when the gun dry fires and no staples exit the gun.
  • Use only full staple strips in the staple gun. The spring in the magazine clip is calibrated for the correct pressure on a full staple strip.
  • Do not release the magazine clip quickly if it is not in a stop position. Doing so will place undue force on the spring in the staple channel and can damage the spring.
  • Never point a staple gun at a person and pull the trigger. The staple will shoot out of the end and can cause injuries..
