Lightweight Composite Material Buried Mounting Platforms for CUBE™ Outdoor Equipment Enclosures
CPAD Modular Mounting Platform
Charles Composite Pads (CPAD) are economical alternatives for concrete pads which eliminate on-site work, save time, and eliminate injury risk associated with handling and maneuvering heavy concrete slabs. With today’s compressed schedules to complete network builds, the CPAD solution enables rapid deployment with minimal on-site project planning and coordination. Made from advanced composite materials, CPAD are extremely durable (i.e., won’t crack over time), lightweight, and simple to install. With available options for both small cell and macro cell deployments, there is a CPAD solution for all your wireless deployment builds. CPAD are custom designed to fit the mounting pattern as well as cable ingress/egress ports of the Charles enclosure that is placed on top. 

CPAD may be used for other applications or for mounting cabinets or products from other equipment manufacturers. To make installation of these devices simpler, a line of universal CPAD have been created. Universal CPAD can be quickly customized in the field to support other manufacturers' cabinets and generators.

CPAD Applications

  • Small Cell
    A variety of CPADs have been designed to match Charles groundmount Small Cell cabinet and shroud solutions

  • Fiber Backhaul


  • Line Power


  • Universal Ground Mount Cabinet & Generator Platforms
    The Universal CPAD supports cabinets and generators from all manufacturers. The cabinet or generator's mounting holes are used as a template, with holes being drilled for perfect placement, and then anchors installed from the top.

Proprietary Composite Construction

Composite materials and coatings have been tested by Environ Labs, a certified Nationally Recognized Test Lab in Minneapolis.  Materials are Fully compliant to SCTE/ANSI-77 2013 Standard which covers Impact Resistance, Flammability, Sunlight Exposure, Chemical Resistance (includes Telcordia GR-902 Chemical list), Brush Fire Test, Water Absorption and Tier 15 and Tier 22 Load Ratings

Standard pads can accommodate up to 8,000 lbs of equipment.  With additional bracing, pads can be made to hold 20,000 lbs. 

Composite Pads with attached cabinets and shrouds have exceeded GR-487 Overturning Moment test requirements (simulating 150 mph wind force)

CPAD Basic Installation Procedure

CPAD Installation Photos
  1. Dig a hole 2” larger (minimum) than the perimeter of the pad, approximately. The hole must be deep enough so that the composite pad will be buried to within 1” to 2” above the pad line at the highest ground point. When calculating the depth of the hole, be sure to include 6” for a bed of gravel. 

  2. Route the conduit to the hole. Place the conduit so that it can be easily installed through the openings in the composite pad into the cabinet. 

  3. Backfill and tamp the ground around the conduit and the mounting hole, ensuring that it is securely compacted and level to avoid heaving and conduit movement issues in the future. 

  4. Fill the hole with approximately 6” of pea gravel. Tamp the gravel so that it is compact and level to ensure proper drainage and leveling of the pad. 

  5. After the hole has been properly prepared, place the Composite Pad so that the holes in the pad line up with the conduit. Square and level the pad. 

  6. It is recommended practice to drive 16” to 18” screw anchors through the flange of the pad and into the ground through the provided holes (Composite Pad Screw Anchor Kit sold separately; Note: if the provided anchor holes in the pad flange line up with conduit, the installer can drill a new 1.5” hole in the pad flange up to 8” in either direction from the original hole and install the screw anchor in the new hole. Ensure that the pad is still level. 

  7. Backfill around the pad. Tamp the dirt every six inches of depth to ensure that it is properly compacted. Ensure that the pad is still level. 

  8. Before cabinet installation, cut off conduits just above the gravel line. This ensures that there is the full space in the cavity below to route and manage the cables. The cavity also allows fiber slack storage.
