SPP post-purlin connectors - the ideal solution for tensile connections or wood connections with combined load types, such as post-purlin connections. SPP is a retensionable wood connection that can be loosened and removed without problems. According to the ETA, a straight screw connection is permitted even in cross-grained wood. This makes it possible to increase the tensile load-carrying capacity by increasing the effective thread length at the wood screw.
