The A-LOK Primary Precast Invert System provides an economical and efficient method of manufacturing quality
A-LOK Products, Inc.rimary Precast Invert System provides an economical and efficient method of manufacturing quality concrete inverts in pre-cast concrete manholes. The system allows the bench to be formed during the initial manufacturing of the base. The equipment consists of a cast "invert" plate, which allows a 1-in. per ft. slope across the bench to the channel. The channels are formed by interchangeable fiberglass inserts that are "quick bolted" to the invert plate. The inserts are coated inside and out to prevent delamination in steam environments. The hub areas of the insert are designed to facilitate match-ups between pipe and manhole channel inverts. The equipment is now available for pipe sizes 8-in. through 12-in. in the two-way configuration and 8-in. for standard three-way tee structures. It is available for both 5/8-in. and flat grades. Other features include:

•Easily adaptable to existing casting equipment.
•Similarity to standard set-up procedures makes the system simple to use and time efficient.
•Eliminates labor, space and equipment necessary for secondary pour.
•Helps control products damage by reducing in-plant handling of the product.
•Provides a smooth uniform channel not obtainable by secondary pour equipment.
•Compatible with boot or pipe to manhole connectors.
