Another benefit of pre-installing door hardware is that it can reduce product damage on-site because everything for a pre-install job is completed before shipment and delivery. Pre-installation can also help eliminate shrinkage (lost or stolen hardware items onsite), misused products, or the need to correct mistakes when materials are lost or when incorrect hardware is installed. Pre-installation of hardware will also drastically reduce the amount of onsite waste produced (approx. 80%) vs. individual boxes and skids of hardware arriving loose onsite and needing to be disposed of after unboxing. In summary, pre-installing commercial door hardware on doors can save time, reduce punch-list complications by catching errors/wrong product prior to jobsite delivery, reduce onsite labor costs, drastically reduce jobsite waste and minimizes product damage on-site.
