trigger fire staple gun

Heavy‑duty staple guns commonly use T50 staples in these sizes: 1/4", 5/16", 3/8", 1/2", and 9/16". Some heavy‑duty kits specifically include 3/8" T50 staples.

Some heavy‑duty kits include basic accessories such as a staple puller and a supply of staples — for example, one kit lists a staple puller plus 1,000 T50 staples in 3/8" size.

5‑in‑1 staple guns accept a mix of fasteners, typically including flat‑crown T50 staples, thin‑wire JT21 staples, round‑crown T25 staples, and 18‑gauge brad nails; some models also note compatibility with 5/8‑inch brad nails.

Listed weights in this selection range from about 0.94 to 3.6 pounds. Reported overall heights (from product dimensions) range from about 1.14 to 10.9 inches.
