Different timber connections are used for different structural and design needs. Some are traditional and highly visible, while others rely on concealed hardware or engineered steel for added strength and clean detailing. Browse the examples below to learn how each connection works and where it may be used in a timber frame or mass timber project.
A dovetail connection is a traditional concealed wood-to-wood joinery method where one timber is cut to slide and lock into another. It typically drops in from above, creating a clean connection with no visible hardware and no custom steel required.
Commonly used for joist-to-beam, purlin-to-beam, and rafter-to-beam connections where a clean, traditional appearance is desired.
A mortise and tenon is a traditional timber frame connection where a projecting tenon on one timber fits into a matching mortise pocket in another. The joint can be secured with wood pegs, concealed fasteners, or engineered hardware depending on the structural requirements.
Commonly used for post-to-beam, brace-to-post, brace-to-beam, and traditional timber frame connections where strength, craftsmanship, and visible joinery are important.
A Ricon-style connector is a concealed steel connection system that allows one timber member to drop into place from above. It provides a clean, hidden connection with no visible hardware and typically avoids the need for custom steel fabrication.
Commonly used for joist-to-beam, purlin-to-beam, and rafter-to-beam connections, especially when a concealed modern connection is preferred over traditional wood joinery.
A steel post base or saddle is a visible steel connection used to support timber members or connect timber to steel elements. The timber typically drops into or onto the steel saddle and is secured with bolts, screws, or other hardware. Because the steel remains visible, it may be finished to suit the architectural design.
Commonly used for HSS steel post-to-wood beam connections, timber post bases, canopy supports, and structural timber-to-steel transitions where visible steel is acceptable or part of the design.
A steel knife plate is a slim steel plate inserted into a slot cut into the timber or glulam member. It is secured with through-bolts and can be installed from above or below depending on the connection design. Bolts may remain visible or be hidden with wood plugs for a cleaner finish.
Commonly used for HSS-to-timber, glulam beam connections, post-to-beam connections, trusses, canopies, and structural timber-to-steel connections where strong load transfer is required with a more concealed steel profile.
