Compatible with the Staplex® S-630NHL and S-630NHLA triple-headed staplers, these staples and accessories are manufacturer-direct and of the highest quality, offering premium performance. Staples come in two types, type DS standard staples that measure 1/4", or type LL long-leg staples that measure 9/32". Adding a footswitch to your stapler lets you activate the staple action with the tap of a foot pedal, which leaves both of your hands free to handle the papers. And the adjustable backstop accessory lets you change how deep you set in your staples, with precision. Refill your Staplex® S-630NHL staple supply or add versatility to your stapler with these supplies and accessories. Note: The footswitch and backstop must be purchased together to work properly.
