How to Use a Cordless Fencing Stapler? | Load, Depth, Fire

Most fencing wire fails because the staple wasn’t driven right, not because the tool couldn’t handle it. Learning how to use a cordless fencing stapler comes down to three phases: loading and setup, depth adjustment, and firing technique. Skip any one and you will be pulling staples all afternoon.

Loading and Setting Up Your Cordless Fencing Stapler

The most common jam by far comes from backwards staples. On the DeWalt DCFS950 — the dominant model for US rural fencing — pull the staple pusher to the bottom of the magazine until it locks. Insert collated 9-gauge staples from the rear with the legs pointing toward the front of the tool, then release the follower to apply constant pressure. The magazine holds 35 staples, and the tool accepts lengths from 1-1/2 to 2 inches.

Only use brand-specific staples. DeWalt’s 9-gauge stapler cannot fire 16-gauge staples without modification, and generic staples often jam or damage the feed mechanism. If you are choosing between models, our roundup of the best cordless fencing staplers compares staple compatibility and features across every major brand so you match the tool to the fence job.

Setting Depth and Firing Your Stapler

Hardwood needs a deeper drive than pine, and the tool-free depth adjuster on the DCFS950 lets you dial it in without tools. Test fire on a scrap of the same timber before you start on the fence. Adjust until the staple sits flush with the surface but does not sink below it — an under-driven staple won’t hold wire tension, and an over-driven one splits the wood and loses grip. On pneumatic models the adjustment works differently (loosen a cap screw and slide the work contact element), but the logic is the same: test, adjust, test again.

Press the workpiece contact bracket firmly against dry timber — wet wood shrinks as it dries and ejects staples within weeks. Pull the trigger for single-fire placement on corners and tension points, or switch to bump-fire mode for long straight runs where speed matters. Fire staples in a side-to-side or diagonal pattern; never at full horizontal. A horizontal staple aligns with the wood grain and pulls loose under tension from woven wire or high-tensile fencing, while a diagonal staple crosses the grain and locks into more fiber. For batten attachment, space staples 6 to 8 inches apart along each batten.

Keep the battery locked in and carry the tool by the handle, never with your finger on the trigger. Remove the battery before clearing jams; the DCFS950 has a tool-free stall release lever on top for that purpose.

Common Mistakes That Waste Time

• Wet timber. Staples pop out as the wood dries, no matter how well they were driven.
• Horizontal placement. The staple has no purchase across the grain and fails under tension.
• Wrong gauge. 16-gauge staples will not feed through a 9-gauge tool, and forcing them damages the magazine.
• Skipping the depth test. Under-driven staples hold nothing; over-driven ones split the wood surface.
• No eye protection. A snapped staple at speed is a serious hazard. Always wear ANSI Z87.1-rated safety glasses with side shields and ear protection during extended use.

FAQs

Can you use a cordless fencing stapler on wet wood?

Not recommended. Staples driven into wet timber work loose as the wood dries and shrinks, leaving fence wire slack within weeks. Always staple into dry, seasoned wood for a permanent hold that lasts the life of the fence.

What gauge staples does a cordless fencing stapler take?

Most heavy-duty cordless fencing staplers, including the DeWalt DCFS950, use 9-gauge collated staples. Lighter models such as the Freeman PE20VTFS16 use 16-gauge staples. Check your tool’s specification — the two gauges are not interchangeable without modification.

How do you clear a jam in a DeWalt fencing stapler?

Remove the battery first. Use the tool-free stall release lever on top of the tool to release tension. Open the magazine, remove the jammed staple, reload, and reattach the battery before resuming work. Never try to clear a jam with the battery attached.
