High-Capacity Staples for Optima Staplers

This box contains 2500 Swingline 35550 staples designed for Optima 60- and 70-sheet staplers. The 3/8 inch leg length and 1/2 inch crown handle thick document stacks. Silver steel wire provides strong penetration for secure fastening. Each strip holds 125 staples for continuous loading.

Replacing Standard Staples for Heavy Stacks

Standard staples often jam or fail to penetrate stacks approaching 70 sheets. These high-capacity staples use stronger wire and a longer leg to drive through dense paper cleanly. The upgrade is worth it when your current staples bend, jam, or leave corners loose on large reports. They match the exact specifications required by Optima heavy-duty mechanisms.

Simple Reload with Fewer Interruptions

Loading is straightforward: open the stapler magazine and insert a full strip of 125 staples. The box supplies 2500 staples total, reducing the frequency of reloads during high-volume tasks. Jams usually occur only if the stapler's anvil is misaligned or if the paper stack exceeds the 70-sheet rating. Ensure the stapler model matches the Optima 60- or 70-sheet class for reliable feeding.

Questions about this item

Will these 3/8-inch leg staples fit my Optima 70-sheet stapler?

Yes, the 35550 staples are made for Optima 60- and 70-sheet staplers, with a 1/2-inch crown and 3/8-inch leg length that match the magazine specifications.

How do I load the 125-staple strips into the magazine without jamming?

Open the magazine, lay a full strip flat with the legs pointing down, and push it to the rear until the follower clicks; the most common error is inserting a partial strip or reversing the leg direction.

When will I need to replace the box of 2500 staples?

A box of 2500 staples lasts for 2500 individual fastenings; with 70-sheet capacity staples you will use fewer strips per job, so replacement depends on your daily sheet volume.
