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 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.
