Profile: Craigg Manufacturing Corp. manufactures in-floor access enclosures and pit systems. We provide access to under-floor mechanicals, water piping and valves, drainage hubs & piping, electrical wiring & controls and refrigeration piping & controls. Our adjustor is an in-floor access enclosure system, which simplifies the installation of underfloor mechanicals. Our adjustor system eliminates constant maintenance problems with cracking, breaking & lifting of floor coverings around frames and covers. Our products serve as a durable, lightweight prefabricated waterproof liner, which replaces the need to form and pour concrete or build costly access pits on the project site.
