heightec Inspection Notice:


During an IRATA Level 1 training course a candidate’s chest ascender, a heightec Twist (D42) released the rope during a wide re-belay maneuver when the ascender was in the bottom of the ‘V’ of rope and both sides of the ‘V’ were loaded. No one was injured during the incident.


Checks have indicated that twist ascenders manufactured before December 2011 could be susceptible to a similar issue. Compact and Pulsar ascenders are not affected.

Action required

Twist ascenders manufactured before December 2011 may be identified by their batch number, e.g. 1211, where the first two digits signify the month (12 = December) and the last two digits signify the year (11 = 2011).

If you have any twist ascenders manufactured before December 2011 measure across the body of the device to the side of the rivet head as shown in the photo. The shortest distance between the two points shown should be 26mm or less.


If the dimension is greater than 26mm then quarantine the device and return it to heightec for free replacement. Alternatively, contact heightec Technical Manager Chris Edmondson on 01539728866 or Email, chris.edmondson@heightec.com. 7/10/15
