A bolted hinge assembly is provided for a waterbox cover (a 'waterbox hinge assembly'). The waterbox hinge assembly generally does not require welding on the waterbox cover or the heat exchanger in an HVAC system ('HVAC unit' hereinafter). Further, the waterbox hinge assembly may be installable to the HVAC unit without removing the heat exchange fluids (e.g., water, refrigerant, etc.) from the HVAC unit. In some cases, the waterbox hinge assembly can be installed on an HVAC unit without removing any bolts from the waterbox cover. Once installed, the waterbox hinge assembly can be left in place so that it can be reused anytime the HVAC unit is serviced.

Stair tread overlay

A stair tread overlay and a riser overlay made from solid wood for fitting over a conventional, exposed wooden stair having a generally rounded nose like those found in most residential general construction staircases and prefabricated staircases. The tread overlay and riser overlay cover the exterior surface of a conventional wooden stair from stringer to stringer to hide a construction grade stair tread and riser below that are made from a composite material or unsalvageable hardwood to present an attractive, solid wood surface that is finishable.
