Diagram of a standard concrete connector showing two wooden beams labeled Connection A and Connection B, with dimensions and labels V.1, V.2, T, d.1, d.2.
A table displaying connection capacities in pounds for various types of screws and pins, organized by connector number, number of screws and pins, timber species, load duration, and other specifications.
Table showing specifications for various timber connectors, including types, number of screws and pins, species, load duration, and electrical performance metrics.
Diagram of a round connect connector showing two connection types, with labeled measurements and loading directions for each connection.
Table comparing connection capacities for different timber species, including species such as Eastern White Pine (EWP), Douglas Fir (DF), and Red Oak (R. Oak). It lists screw counts, pin counts, load durations, and capacities in pounds for 5-inch and 8-inch diameter connectors.
Assembly diagram showing a wooden post with a mounted angled wooden beam secured with screws, illustrating connection orientation with labeled tension (T) and vertical (V) forces, and detailed technical drawing of the connection with measurements and drilling instructions.
Technical drawing of connector plates showing pin connection layout, with measurements and angles, for both 8x and 6x configurations.
Table showing connection capacity in pounds for fire tower engineered timber, including different types of connectors, screw counts, pin counts, timber species, load duration, and related specifications.
Diagram showing how to connect a connector to concrete, with illustrations of different screw hole patterns and loading directions.
Table of service-level connection capacities for fire-tube timber connectors, listing details such as connector size, number of screws and pins, timber species, load duration, and resulting capacities for T, V1, and V4.
Two images of HDPE 1-inch risers used in concrete construction. The first image shows a person installing a riser into a concrete form, and the second image displays a completed riser with multiple bolt holes for attachment.
Technical drawing of a connect 3-way connector used for connecting wooden beams, showing connection orientation and spacing requirements.
Table showing service-level connection capacity in pounds, detailing post side and beam side connection capacities based on different post sizes, timber species, and load durations.
Diagram showing 4- or 5-way connectors and corner connectors used for fire-resistant timber construction, with annotations of load directions and connection types.
