The CAP RF ® (Patent-Pending)

CAP Game-Changing Technology

CAP RF - Composite Manhole Cover with RFID, GIS, Asset Tracking

First of its kind, compression-molded, composite manhole cover with Radio Frequency Identification...ENCAPSULATED IN  SUBSTRATE!!!  The CAP RF® enables the engineers and operators to store and retrieve manhole data and in-hole asset information.  Currently, engineers need to open the cover or travel back to the office, but with the CAP RF ®, information is retrieved at the point-of-use...and without opening the cover.

What is Encapsulation?

CAP molds the RFID hardware into the raw material compound during pressing process!  This removes worries about the RFID tag breaking off or getting damaged by the corroding environment under the cover.  

RF and AMR Signals Pass Through Composites

CAP RF does not need antenna shields

Metals absorb electromagnetic waves requiring penetrating and protruding antenna.  Waves pass through composites!  Special antenna shields to protect damage from impact (e.g. snow plows, handling from contractors, etc.) are not necessary.  Infiltration and Inflow through antenna holes can be avoided. 

Locate CAP RF® Cover With Radio Waves!

The encapsulated RFID Technology can be located with RF Scanners – No metal pieces fastened to the covers for metal detectors are necessary!    


Example Situations:


•Asphalt Overlay

•Hidden in Landscaping

•Obscured by Uncut Grass
