If you have a heavy-duty staple gun, one of the first things to check before starting a project is whether the staples you have will fit the tool. Staple sizes and crown styles can vary, which can make choosing the right staples confusing.
The Surebonder 5650 All-in-One Heavy Duty Staple Gun is designed to accommodate multiple heavy-duty staple types and sizes, including staples with leg lengths ranging from 1/4-inch to 9/16-inch.
In this guide, we'll explain what staples the 5650 uses, how crown styles differ, how to choose the right staple length, and what types of projects you can tackle with this versatile staple gun.

What staples fit the Surebonder 5650?
The Surebonder 5650 is designed to work with compatible heavy-duty staples in several staple formats. It supports leg lengths from 1/4-inch to 9/16-inch and accommodates narrow crown, wide crown, and power crown staples.
| Staple type | Leg length | Typical applications |
|---|---|---|
| Narrow crown | 1/4"–9/16" | Upholstery, trim, general fastening and repair |
| Wide crown | 1/4"–9/16" | Insulation, sheathing and general construction |
| Power crown | 1/4"–9/16" | Heavier-duty fastening applications |
The 5650 is also designed to accommodate compatible staples from several common staple systems, including Arrow T50-style, Stanley-style, Powershot-style, Duo-Fast-style and Bostitch-style heavy-duty staples.
Keep in mind that compatibility depends on the staple's dimensions and format, not simply the brand name. Always check the specifications of the specific staples before use.
Does the Surebonder 5650 use Arrow T50 staples?
Yes. The 5650 is compatible with Arrow® T50® style staples, making it an option if you already use T50-style staples for your projects.
The benefit of the 5650 is that you're not limited to one staple system. You can choose compatible staples based on the material and application.
What's the difference between narrow crown, wide crown and power crown staples?
If you're new to heavy-duty staplers, crown styles can be confusing. The crown is the top portion of the staple that connects the two legs. Different crown widths are suited to different types of fastening.
Narrow crown staples
Narrow crown staples have a smaller crown and are often used when you want a more discreet fastening point. Common applications include upholstery, trim work, furniture repair and general fastening.
Wide crown staples
Wide crown staples cover more surface area across the material. A .500-inch wide crown can be useful for applications such as insulation, sheathing and general construction where additional coverage is helpful.
Power crown staples
Power crown staples have a larger crown and are intended for heavier-duty fastening applications where broader material coverage is useful.
Choosing between crown styles depends on both the staple gun and the material you're fastening.

How do you choose the right staple length?
Once you've chosen the appropriate staple format, the next consideration is leg length. The 5650 supports staple lengths from 1/4-inch to 9/16-inch.
The right length depends on the thickness and type of material you're fastening. You want enough penetration to create a secure hold without using a staple that is unnecessarily long for the application.
- 1/4-inch to shorter lengths: Useful for thinner materials and lighter fastening applications.
- Medium lengths: Common for upholstery, furniture repair and general workshop projects.
- Longer lengths: Useful when additional penetration is needed for thicker materials and heavier-duty fastening.
Always consider the material you're fastening and the application before selecting a staple length.
What can you use the Surebonder 5650 for?
The 5650 can be used for a range of home, workshop and jobsite projects. The appropriate staple type and length will depend on the material you're working with.
- Upholstery and furniture repair
- Insulation installation
- Vapor barrier installation
- Underlayment
- General home repair
- Workshop projects
- Woodworking
- General construction fastening
Whether you're repairing furniture, working with insulation or tackling a construction project, choose the staple format and length that best matches the job.

Why choose an all-in-one heavy-duty staple gun?
Many heavy-duty staple guns are designed around a specific staple format. If you work on different types of projects, that can mean keeping multiple tools on hand.
The 5650 is designed to give you more flexibility by accommodating compatible heavy-duty staple formats in one tool. That means you can switch between staple types and lengths based on the application instead of choosing a separate staple gun for every project.
For DIYers, makers, upholstery users and professionals who work with different materials, that flexibility can make it easier to keep one heavy-duty staple gun ready for a variety of jobs.
Who is the Surebonder 5650 for?
The 5650 is a useful option for anyone who regularly works with different heavy-duty staple formats.
- DIYers: Keep one staple gun available for a variety of home repair and improvement projects.
- Upholstery and furniture users: Use compatible staples for fabric, furniture and repair projects.
- Contractors: Work with different staple formats for different materials and applications.
- Workshops: Have one tool that can accommodate multiple compatible staple types.
If you typically use one staple type for a specific application, a single-format staple gun may be all you need. If you regularly switch between staple types, the 5650 gives you more flexibility from one tool.
