Overview
Driving narrow crown staples from an air supply, this Bostitch SX1838K is a narrow crown finish stapler sold with a quarter inch air fitting and a carrying case. It works in a semi-automatic mode from a full strip of fasteners.
The kit pairs the tool with a fitting and a case, so a compressor line can be connected and the stapler stored straight away. The limitation is missing working data: no staple size range, no air pressure and no warranty are given.
Who it's for
Someone fastening trim, panels or thin stock with an air compressor already in the shop is the target. A buyer who needs cordless operation, or who must confirm staple lengths first, should check the manual or another model.
Pros and cons
- Narrow crown finish fasteners
- Air fitting and carrying case included
- Semi-automatic firing mode
- Needs an air compressor
- Staple length range not listed
- Warranty not stated
Performance notes
Staples are driven by compressed air, so firing consistency depends on supply pressure and a compressor that can keep up. Semi-automatic mode fires with each trigger action rather than in a continuous stream. Narrow crown fasteners are the finish-work format.
