The A-LOK Magnetic Angle Tape Measure allows one person to safely set angles quickly and accurately for hole or connector placement on a precast mold. Eliminates the need to convert angles to inches. Available in 48” through 144” OD.
Rock Valley Storm Sewer Job
A-LOK STM connectors were used for this watertight storm sewer job in Rock Valley, Iowa. The precaster showed the engineer pictures of two other STM box jobs he did in the past year. The engineer liked the idea and convinced the city to use them. Compression style watertight connections were made to accommodate the following sizes of pipes: 8” PVC, 15”, 18” 24”, 36” and 48” RCP. All were cast into square structures with sizes ranging from 2’x2’ to 6’x8’ inside. The city of Rock Valley now has written storm water specifications for watertight pipe penetrations in boxes using A-LOK STM connectors.
This was a stormwater job in Toledo, Ohio. Watertight connectors were chosen over grouting to speed up the installation. The interesting thing about this job was the 42" RCP had an OD of 51.25" which is the very biggest size suggested for the #1640 A-LOK Connectors cast into these manholes. However, the extra flexibility of the A-LOK Premium connector made the installation of the pipe very quick, requiring minimum force.
A-2000 PipeThis manhole was installed in Payne, Ohio. The picture shows a 36'' A-2000 pipe, with a smooth over sleeve, in position over the top of the pipe corrugations. It's held in place by a piece of 3/4'' plywood that fits down in the corrugation. This keeps the smooth oversleeve from moving during installation of the pipe into the #1310, A-LOK Premium Connector. The oversleeve is lubed, the pipe is centered in the connector and was pushed home.
During the late 1980’s in Bar Harbor, New Jersey there was a real problem with Hydrogen-Sulfide gas when the unlined manholes they installed a few years early needed to be replaced. They tried fiberglass manholes which lasted less than 2 years. The local municipality, Long Beach Island, then installed sixteen of our Dura-Plate 100 Liners for the manholes. Below is a picture of the manhole with our liner still protecting the manholes over 20 years later.
