We’re excited about the quality and functionality of our manhole security systems, and we’d like to help you understand them better. If you can’t find the answer you’re looking for here, feel free to contact us.
The Stabiloc™ system is unlike any other device available worldwide. Most products that are in use today rely on age-old technologies which are expensive and difficult to use. In most cases these type of solutions have been used simply because there was no other alternative – until now. Stabiloc™ is proudly manufactured in the United States by expert craftspeople and uses principal mechanics to secure a manhole cover to its respective frame.
Yes. By implementing the Stabiloc™ locking system to your new or existing infrastructure, you will be using a state of the art product which is manufactured with the strongest metal alloy available today. The entire Stabiloc™ locking system is custom made and is virtually impenetrable.
Yes. Modification of the manhole cover is required in order to receive the Stabiloc™ locking system. However, there is no requirement to modify the manhole frame. You can contact your manhole cover supplier and ask them if their manhole covers are equipped to receive the Stabiloc™ locking system.
The Stabiloc™ assembly consists of a flanged lock body, a trunnion, an anchor bolt, receiver, lever arm and a tamper evident UV resistant cap – which keeps the Stabiloc™ bolt-head free from dirt and debris.
We recommend that two Stabiloc™ units are needed for each cover. Units secured to opposite sides of the manhole cover have proven to be the strongest method of securing the covers to the frames. If you have a hinged cover, only one Stabiloc™ is required.
All components of the Stabiloc lock assembly are made of cast ductile iron. Before assembly, all components, except the stainless steel springs, receive a coating of ArmorGalv. ArmorGalv is a patented process that takes a zinc powder and turns it into a gas by heating it in an oven. The components are then placed into the oven and slowly rotated for several hours receiving an even coating 6 mils thick that provides outstanding corrosion resistance. Our Stabilocs are warrantied against failure due to corrosion.
Assuming that the manhole covers are centrally located (warehouse) the average time needed to machine a manhole cover is approximately forty-five minutes to one hour if performed by a CNC lathe machine. Other machining methods (drill press) would lengthen this time frame.
Factoring in the time for going to the location to remove the manhole and then ship it to the machine shop, if we were to receive the covers and then machine them for you, anticipate a 2-4 day turnaround time depending upon transit time.
Most authorities/cities/facilities have a number of “spare” covers in their stock depot because manhole covers are routinely stolen. Most customers choose to implement a “rip and replace” system whereby covers are taken from existing stock, machined and then exchanged. Repeat this process and develop a time line by which to install the system. An aggressive implementation schedule can realistically install a complete network (200+ Covers) in approx. six weeks.
