The STINGER HT38 Hammer Tacker is an ideal tool for installing roofing felt, housewrap and insulation. The HT38 is light and easy to maneuver—but constructed with heavy-duty steel for durability. The tool has an anti-slip, ergonomic rubber handle to also help with ease of use. The tool features a quick-load magazine that holds 168 staples. The manufacturer recommends using STINGER 10mm A-11 Staples for best performance. However, compatible staple sizes are 6mm – 10mm.
