Concrete & Rock
Markers
| Cl Concrete Marker The Berntsen Model Cl Marker is based on the design of the US Army Corps of Engineers Type-1 disc. The taper and split style stem is approximately 3" (76 mm) long and assures solid and positive anchoring in grout, epoxy or concrete. Available in aluminium or bronze, 3-1/4" (83 mm) or 4" (102 mm) diameters. Installation: Tap into wet concrete or epoxy. |
 |
| CD2 Concrete Marker Model CD2 is orbital forged for strength from 6000 series aluminium or unleaded bronze and will, therefore, not crack, chip, or break. It is available only in popular 2" (50.8 mm) diameter domed top and has a 2" (50.8 mm) long stem that is .76 (19.3mm) in diameter. Installation: Tap into wet concrete or epoxy. |
 |
| RTI Rock Tablet Marker The Rock Tablet, Model RT-1 is a variation on the concrete marker theme. The RT1 offers more resistance to twisting. Available in bronze or aluminium alloy as a sand casting (three legs) and an aluminium or bronze forging (four legs, slightly different design). Top diameter is 3-1/4" (82.5 mm) dome or flat. Installation: Tap into wet concrete or epoxy. |

Survey Caps
for Rebar & Pipe
| Survey Caps for Rebar Survey caps for rebar with insulators ... another first from Berntsen. A good rebar cap should not " wobble" when tapped onto the rebar. This is not possible with shallow conical socket, so we use a deep hex socket and 6000 series orbital forged aluminium to help prevent over stretching of the socket during installation of the cap. Berntsens unique insulator-wedge effectively isolates the aluminium cap from the steel, de-forms around the ribs of the rebar, and fills the cap's hex shaped socket for a super-tight compression fit. As with all Berntsen monuments and markers, survey caps for rebar are available with your name and number. Various top diameters including (A) 3-1/4" (82.5 mm), 2-1/2" (63.5 mm),2" (50.8mm), and 1-1/2" (38.1 mm) are available to fit the sizes of rebar most often used by professional land surveyors ... (C) 3/8" (9.5 mm), 1/2" (12.7 mm), 5/8 (15.9mm), 3/4" (19mm), 7/8 (22.2mm), and 1" (25.4 mm). |
 |
| Survey Caps for Iron Pipe Berntsen orbital forged aluminium survey caps for iron pipe with insulators attach to pipe with a few sharp hammer blows with a urethane hammer. The virtually straight walled socket and plastic insulator wedge create a strong compression fit between the pipe and the cap. Popular 2" cap diameter is available to fit either 3/4" (19 mm) ID or 1 " (25.4 mm) ID standard pipe. |
 |
| PERMAMARK Plastic Survey Caps PERMAMARK caps are easy to tap on to and are available with your name and number. Four sizes fit inside water pipe or over rebar: 3/8" rebar or 1/2" pipe. 1/2" rebar or 3/4" pipe, 5/8" pipe or 1 " pipe, and 3/4" rebar. |
 |
| Rebar Drivers Berntsen rebar drivers are made from strong, heat treated steel and provide an ample 2" striking surface for driving 1/2", 5/8", or 3/4" rebar. Use with urethane faced or conventional hammer. |
