Fundilock - Copper cable theft solution for manhole covers

New antitheft system designed to secure any manhole cover and avoid the cable stealing, wire theftor telkom cable theft or copper cable theft, thanks to its geometry and availability of diameters and qualities. It is a patented and innovative product that is being installed in many places including USA and some European countries.

Nuclear power plants such as ASCO, BANDELLOS, Almaraz Cáceres and Trillo in Madrid as well as several city councils rely on Fundilock to tackle the security problem that exists with the theft of caps and what they protect, such as wiring, optic fiber, etc.

We can also manufacture unique wrenches and screws for orders greater than 1000 units, in this way we make sure to have a unique system of wrench and screw, so that the designs are changed by countries and communities.

Wet installation

fundilock 6 1 - Look for the flattest area next to the frame of the manhole cover to install the Fundilock washer. In case of unevenness it will be necessary to pave with anchoring cement until the outer surface reaches the level of the cover.
2 - If the cover is hinged, only a Fundilock will be placed on the side of the opening. If it does not have a hinge, 2 to 4 Fundilocks will have to be installed.
3 - Choose the size of the washer (70mm, 100mm, 130mm, 150mm) that allows to protect the manhole cover + frame.
fundilock 75 - We start by drilling vertically using a 25mm drill bit for concrete, deepening about 100mm depth.
fundilock 86 - Aspirate the dust produced to leave the hole clean and fill it with bonding material.
6.1 – Chemical dowel
fundilock 96.2 - Composite anchor cartridges
fundilock 106.3 - Self-levelling anchoring cement type Sikadur 42
fundilock 117 - We take the special steel union plug piece, 12mm wide x 80mm long, which is composed of a threaded rod welded to a bush. This piece is inserted inside the hole made in step 4, 25mm wide x100mm length, we press it to get it imprisoned until a perfect leveling with the cover that is going to be protected.
fundilock 128 - Once the bonding material has been sealed with the imprisoned plug piece, place the neoprene washer over the hole to prevent moisture from entering, and on the top of it, the Fundilock washer of the chosen size. Once aligned, we will use the supplied 12mm wide x 100mm long screw, that will be cut to fit perfectly to the upper limit of the Fundilock washer.
fundilock 139 - We will use the supplied three-pronged wrench, with a recommended tightening torque of 44Nm. The three-pronged wrench is manufactured so that any fixed, monkey wrench or torque wrench can be used.
