In their words

Why Rocket builds on SPEC

“We chose to collaborate with SPEC Toolbox because it is a clear, complete tool for our carpenter customers. It centralizes all the technical data needed for timber construction in one place. With SPEC Toolbox, our clients can specify our screws directly in their calculations, which lets them secure their technical choice on their own. For us, that is exactly the point of this partnership: bringing concrete solutions to the whole timber industry.”
