Product Description
The Simpson PFDS28B Double 2x8 Galvanized Post Frame Double Saddle Hanger is a top-flange saddle hanger from Simpson engineered for post-frame construction applications that require solid double 2x8 joist support. Dome-shaped joist nail holes guide nails into the proper installation angle, while a folded seat raises the 2x joist slightly above the seat radius to enable a tighter connection to the back of the hanger. The solid, one-piece top flange allows for accurate and fast installation, making this saddle hanger a dependable choice for barn framing, agricultural buildings, and other post-frame structures where connection integrity is critical.
Key Features
- Installation prongs for quick hanger placement - reduce setup time in the field by holding the hanger securely in position before fastening, speeding up the overall framing process.
- Patented double-shear nailing design - distributes the load through two points on each joist, delivering greater connection strength with fewer nails so you use fewer fasteners without sacrificing structural integrity.
- Dome-shaped joist nail holes - guide nails into the proper installation angle automatically, reducing the risk of misdriven fasteners and helping ensure a code-consistent connection every time.
- Folded seat design - raises the 2x joist slightly above the seat radius to enable a tighter connection to the back of the hanger, improving overall joint rigidity in post-frame assemblies.
- Solid, one-piece top flange - allows for accurate and fast installation by providing a stable bearing surface that seats consistently against the header without adjustment.
- Made from 20-gauge steel with G90 zinc galvanized coating - provides extra corrosion resistance, making this double saddle hanger suitable for demanding post-frame construction environments where moisture exposure is a concern.
- Designed specifically for double 2x8 joist members - ensures a properly sized, load-rated fit for back-to-back 2x8 applications without field modification or guesswork.
Why This Product
- Faster installation with fewer fasteners - the combination of installation prongs and the patented double-shear nailing design means you can set hangers quickly and achieve a strong, load-distributed connection using fewer nails than conventional single-shear approaches.
- Built-in nail angle guidance for consistent results - dome-shaped nail holes take the guesswork out of fastener placement, helping crews drive nails at the correct angle on every joist, reducing callbacks and rework on post-frame projects.
- G90 galvanized protection for long-term durability - the zinc galvanized finish helps resist corrosion in agricultural and outdoor post-frame settings, supporting the long-term performance of the connection without requiring additional protective treatment.
- Engineered fit for double 2x8 post-frame construction - purpose-built geometry and a folded seat that tightens the joist-to-header connection make this hanger a reliable choice for purlin and rafter framing in pole barns, equipment shelters, and similar structures.

Frequently Asked Questions
What member size is the PFDS28B designed for?
The PFDS28B is specifically designed for double 2x8 joist members, making it ideal for post-frame construction projects requiring back-to-back 2x8 support.
What fasteners are required to install the PFDS28B?
The PFDS28B is installed using either 0.148 in. x 1-1/2 in. nails or 0.148 in. x 3 in. nails. Note that 0.148 in. x 3 in. purlin nails must be driven at an angle through the purlin into the header, while 0.148 in. x 1-1/2 in. purlin nails are driven at an angle into the purlin but do not penetrate into the header. Combining top nails with purlin nails is recommended to achieve full table loads.
How does the double-shear nailing design benefit the installation?
The patented double-shear nailing design distributes the load through two points on each joist, providing greater strength with fewer nails compared to conventional single-shear designs. This results in a more efficient and structurally sound connection.
What corrosion protection does the PFDS28B have?
The PFDS28B features a G90 zinc galvanized coating, which provides extra corrosion resistance, making it suitable for demanding post-frame construction environments where moisture exposure is a concern.
