How is STABILOC different from other manhole cover containment devices?
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 types 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.
 
Will STABILOC prevents unauthorized entry to my critical infrastructure?
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.
 
Do I have to modify my manhole cover?
Yes. Modification of the manhole cover is required in order to receive the STABILOC system. 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 system.
 
How many STABILOC units do I need for each cover?
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.
 
What is the STABILOC system made from?
Each STABILOC system is crafted form 17-4 Military grade stainless steel. Precipitation hardened stainless steels are widely used as structural materials for chemical and power plants because of their balanced combination of good mechanical properties and corrosion resistance. 17-4 PH stainless steel is a martensitic stainless steel and is strengthened by a precipitation of copper. We have selected these materials because of their longevity, durability and superior strength.
 
How much time is needed per manhole to machine it?
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, what is the total turnaround time per manhole?
If we were to receive the covers and then machine them for you, anticipate a 2-4 day turnaround time depending upon transit time.
 
Who provides for the replacement manhole cover, while the original is being machined?
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.
 
What does the STABILOC system consist of?
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.
 
What is STABILOC RFID?

Radio Frequency Identification - refers to the technology that uses devices attached to objects that transmit data to an RFID receiver. These devices can be large pieces of hardware the size of a small book like those attached to ocean containers or very small devices inserted into a label on a package. RFID has advantages over bar codes such as the ability to hold more data, the ability to change the stored data as processing occurs, does not require line-of-sight to transfer data and is very effective in harsh environments where bar code labels won't work.

A form of identification that does not require line-of-sight (unlike infrared or portable data terminals). There are usually three components: antennae (coils), reader transceiver with decoder, and transponder (tag).

In operation, the reader sends out a signal that activates the tag and allows data to come into or leave the transponder's memory. When a tag is within range this signal from the receiver is sensed and information from the transponder is sent to the receiver. In reverse, the transponder can also accept information. The tags can be quite small and can be powered from the radio-frequency energy of the reader.

The optional STABILOC RFID system consists of a handheld reader, an antenna, and software to program STABILOC RFID microchip embedded seal caps. With this exclusive RFID system, a city will have the means to monitor the activities of its maintenance staff and ensure maximum efficiency and compliance with governmental leadership objectives.

Additionally, an optional biometric interface with the servicing technician and the STABILOC RFID reader can be established utilizing an authorized servicing technician's thumbprint. An encrypted code in the embedded RFID microchip cap links the biometric interfaced reader with a central office and the individual taking the reading. Without an established biometric interface, the RFID reader is rendered useless.

As the STABILOC embedded RFID chip characters are read, an optional GPS unit within the reader sends the manhole coordinates, and bio-linked technician's I.D. to a central office in real time via cellular network.

 
What does the STABILOC system consist of?
The STABILOC system consists of the STABILOC Lock Body, a STABILOC Receiver that is attached to the underside of the manhole cover, Custom Socket which is used to tighten and loosen the STABILOC bolt, a tamper evident UV resistant cap - which keeps the bolt-head free from dirt and debris.
