The DMM Shadow offset D is the most compact locking connector in the DMM Professional range and it is impressively strong for its size and weight. Perfect in any confined space or tower climbing situation where the overall weight and size of a system are crucial, the Shadow gives plenty of security reserves whilst feeling featherweight on a harness or in a bag. Hot forged I-beam back for increased strength to weight ratios.


  • Conforms to EN362:2004/B
  • Small Offset D shape provides a very lightweight but strong connector
  • I-Beam section for increased strength to weight ratio
  • Keylock clean nose for snag free connection
  • Hot forged and fully heat treated aluminium for lightness and maximum strength
  • Anodised to BS EN ISO 7599:2010 class 10 E1 sealed for corrosion protection
  • Ideal for general use when weight saving is important
  • Individually marked for traceability

The DMM Multipacks are a simple and convenient way of identifying components within any system.

They are ideal for the training market to aid component identification from a distance, as well as being convenient for work teams and individuals in the safe organisation and operation of fall protection systems.

The classic triple-action, locking mechanism. The Locksafe is almost as simple to use as the Kwiklock, requiring just one extra push-up action of the barrel before the twist, but when locked gives even better protection from accidental opening. This is especially important in situations requiring complex, rope-running systems. A rope under tension may run transversely over other locking mechanisms exposing them to the risk of unlocking. The addition of the third required action dramatically reduces the likelihood of the same rope opening the Locksafe.Top Tip: Keep all Locksafes clean and properly maintained to increase longevity in use.
Locksafe ANSI and CSA
Developed in line with our Kwiklock ANSI mechanisms, we developed an off-axis Locksafe barrel and a Taperlock nose that both dramatically improve the gate push-in and cross gate strength.

All Locksafes listed ending with ANSI meet and exceed the requirements of the new ANSI standard – ANSI /ASSE Z359.12-2009 – which became effective November 2009.

All ANSI certified carabiners are then certified to the requirements of CAN/CSA Z259.12-01 (Class 7211-30)

The Offset D connector shape takes the optimal loading of a D shaped connector ie. load along the spine, and extends the basket outwards to increase gate opening and clipping volume. This adds to the positivity in the hand, especially when wearing gloves. Again, DMM Offset Ds vary dramatically in size from the featherweight Phantom at 94mm upwards.

Every DMM product carries at least the minimum marking requirements as stipulated by CE norms.

This usually involves 2 distinct sets of markings:

Strength and Certification markings
These markings show the breaking strength of the product or component in various situations as well as relevant CE and instructional information. E.g. an alloy connector would show:

  • Gate Closed strength
  • Minor Axis strength
  • Gate Open strength
  • A ‘Read the instructions’ pictogram and the notified body number for quality management system and CE Mark.

Unique I.D. Markings

All DMM metal products carry a unique serial number. The number allows every single item to be individually traced back to its original date and order of production.

The way it works is as follows:


YR –Year of Manufacture
08 –2008
09 –2009
10 –2010
11 –2011
12 – 2012

DAY –The day of the year on which the product was marked
004 –would be the 4th of January
032 –would be the 1st of February
344 –would be the 10th of December

XXXX –Individual serial number
0001 –would be the first component marked on that day
0050 –would be the fiftieth component marked during the day

# – The machine with which the component was serialized
A = Rotary Laser Marker
B or M = Max Box Laser Marker
C = Dot Marker

Example: 081001450A 

Yr 2008 – Day 100 – Serial Number 1450 – Machine A
