Model SU-100N is generally recommended for stapling 20+ sheets of 20-lb. paper or equivalent.  Model SU-100N requires that the proper size staple be used for each stapling job based on the number of sheets of paper (or equivalent material) being stapled as noted below.  In other words, you cannot use the HO-5/8 5/8" Staple to staple 25 sheets of 20-lb. paper because the staple leg length would be too long for that job.

Uses Staplex Type HO-1/4, HO-3/8, HO-1/2, HO-5/8, and HO-11/16" High Speed Staples. (See below for capacities.)

Completely portable. No mounting required.
