Weighing in at only 4.5 lbs., the CS61H1 is a lightweight stapler that drives 18-gauge, 3/8” crown, 5/8” – 1-1/2” staples with plastic caps. Its in-line compact feed system and top-load cap magazine secure the caps while providing optimal line of sight and maneuverability. The cap bypass switch allows the user to drive staples without caps when needed for door and window jambs. The CS61H1 is ideal for installing house wrap, roofing felt, and foam board insulation.
