Buying Guide to Choose the Best Cap Staplers and Nailers

At first, take a look at the most crucial factors to consider before purchasing any cap stapler or nailer. 

Features to consider

  • Cap Nailer Size: Other factors also depend on the size of a stapler. The bigger the size of a cap nail, the bigger magazine it may hold along with a greater number of nails. But, there’s also a chance of being too heavy to easily carry or handle the machine conveniently. Compact machine have better user convenience and more maneuverability. It’s better to pick one with optimal machine size.
  • Nailer Design: There are many variations of cap stapler design, depending on different assigned work types. Some are designed for the DIY purpose, some as heavy-duty machines. You need to choose a design according to your project type.
  • Driver Depth Adjustment: Make sure your nailer comes with the driver depth adjustment feature before going for it. Some machines offer tool-less adjustment features, while in the case of some other, you can do it using a dial or switch. Whichever you do pick, it’ll come as handy.
  • Different Nail Sizes Compatibility: If your nail gun can support different lengths of nails, then you’ll be able to use it for different purposes, for different projects. If you’re a non-professional DIYer, then for sure, you’d want your machine having such a versatile compatibility feature.
  • User comfort: User comfort is much more important than many technical factors. If you intend to use the machine for extended use, you wouldn’t want it to cause fatigue or discomfort. Choose a well-balanced nail gun with a soft rubber grip with additional ergonomic features to ensure user convenience.
  • Trigger Mode: Firing accuracy and speed solely depend on the trigger option. Usually, there’re two firing methods- bump or contact firing and sequential firing. In bump mode, rapid-firing happens and is perfect for continuous mode. On the contrary sequential firing involves better safety. If you’re an expert, then bump mode is going to be a great one for you. 
  • Safety Measures: For successful operation and project completion, you’ve to consider all safety issues. Simple and easy jam clearing mechanism is crucial for faster operation, and also for avoiding misfiring. Again, the adjustable exhaust is a great way of directing away exhaust gas from the user. It’s another vital feature your gun should hold. 
  • Trigger Size: Trigger size should be convenient for user operation. It should be the optimal size so that you can handle it easily even while putting the gloves on your hand. Again, it shouldn’t be much larger to cause problems in carrying, trouble inconvenience in operation.

Use of Cap Staplers and Nailers 

If you’ve roofing underlayment projects or house wrapping related tasks, and you’re planning to use your manual slap stapler, it’s such a wrong move, I must say.

There’s no meaning in going through hassles and extra efforts with manual items when you can make things easy with a cap nailer, right?

Many professionals prefer it to other general nailers due to the extra strength and more protection provided by capped fasteners. Cap stapler helps expand the surface area of the fasteners, thus increasing their holding power. It also contributes to withstand harsh and advert conditions and protect house wrap and fabric from wear and tear. 

For example, in the case of general nailers using wire staples building fabrics can easily get puffed off due to light breezes. It leaves holes around the building that eventually causes a leak. Manual machines like hammer tackers or slap staplers can also damage your building materials, unlike cap stapler and nailer. Cap staplers using plastic caps can keep building fabrics intact even during gusty wind and other harsh conditions. 

Most US states have strict building codes against inferior building or roofing installation practices. Cap staples can overcome such issues as well. You can also use this machine for other applications like home wrapping, carpet padding, synthetic roofing underlayment, roof vent chutes, tar paper covering, etc.
