2 ModelsCTM-2000 - 2000 lb / 10 kN / 1000 kg - PN 36289-0022
CTM-10000 - 10000 lb / 45 kN / 4500 kg - PN 36289-0014
Measures Cables 3/16" - 1" (5mm - 25mm) (OD)
The Check-Line Type CTM Digital Cable Tension Meter quickly measures tension in cable guardrails, guy wires and overhead lines. It installs, measures and removes in seconds. The digital loadcell is highly accurate and requires no lookup or correction tables.
The Fastest Cable Tension Meter
The CTM can be placed on a cable, measure its tension, and removed in under five seconds! There are no complex lookup tables, no conversion charts. The operator can quickly select from 15 different cable sizes and types stored in the CTM's memory. The Check-Tensioning mode graphically displays the current and target tensions for extremely quick setting of line tension. Even the infrequent battery changes are quick.
Broad Application
The CTM can be employed in many industries to ensure proper tensioning. Typical applications include tower and stack guy wires, pretensioned cable barriers, bridges, elevators, winch rope, prestressed concrete, fall arrest systems, aircraft cables and utilities.
- Includes NIST-Traceable Calibration Certificate
- 2 Year Warranty
- Stores calibrations for up to 15 unique wire sizes and types up to 1 inch max. (25 mm)
- CE Certified
- Portable and rugged – designed for outdoor use
- Telescoping handle engages meter quickly with minimal effort
Calibrate each cable diameter installed with the most appropriate sheaves. If two cable types are used of the same diameter (e.g. ½” 7x7 and ½” 6x19), calibrate each type independently if accuracy is critical.
Recalibration: At user discretion. Commonly 24 months but should be more frequently with heavy use. Factory recalibration conducted typically in 2-4 days.
Custom Calibration Available
The CTM can be calibrated with a customer supplied sample if none of the factory calibrated materials are suitable. In this case a 10 ft. sample must be supplied (non-returnable).
Heavy duty plastic construction with custom foam inserts to secure the CTM tension meter and accessories. HIGHLY RECOMMENDED.

Three sheave sizes are available. For most applications one sheave set for the entire assortment of wire they tension will be sufficient. If you need to check tension in both 3/16" and 3/4" rope, then they should order two sheave sets. The operator must use the appropriate sheave set for the wire size and calibration stored. Changing sheaves sets takes about two minutes with the included wrench.

Calibration load may be changed if desired. Higher calibration loads are limited by max. capacity of the sling. If the desired wire size/type does not appear, customer may supply 10 ft. sample of wire to determine if a custom calibration sling can be created (non-returnable). Consult factory for details.
