If your Bostitch MIIIFS stapler is acting up or you're doing maintenance, this little spacer might be exactly what you need. It's the genuine OEM Bostitch part (number 105055), so it matches the original in fit and function. Comes in a simple bulk pack – just one spacer, no frills. Before you buy, double-check your stapler model and consult the manual to make sure this is the right part. It's a common replacement for wear and tear, helping to keep your stapler running smoothly and driving staples consistently. Easy to install if you're handy, or have your office tech take a look. Keeps your trusty Bostitch in service instead of replacing the whole tool. Always good to have a spare on hand if you rely on your stapler daily. Bostitch quality means it'll last. Just a small part, but it can make a big difference in performance.
