Closing the clip on the Belay Master ensures the carabiner is safe for use. It can only be closed when the gate is screwed shut.
When closed, the clip keeps the carabiner in its strongest orientation, prevents devices and knots from moving onto the spine, eliminates possible cross loading due to rotation. This feature makes the Belay Master the perfect belay carabiner for those new to belaying.
Belay carabiner for consistent rope control and compatibility with belay devices
Belay carabiners give smooth and confident belaying with tube and assisted breaking belay devices. They have full section top bars for consistent rope control and reduced rope wear. Their shape resists flipping into sub-optimal orientations when belaying, acting to ensure the carabiner loads along its strongest axis.
Offset D carabiner for optimal loading and ergonomics
D-Shaped carabiners encourage loading in their strongest orientation by forcing loads toward the carabiner spine. An Offset D refines this basic design by extending the top bar, increasing internal volume. This improves handling and compatibility with thick ropes and slings.
Nylon clip ensures carabiner loads correctly
The Belay Master’s nylon clip prevents accidental opening of the locking mechanism, and ensures the carabiner loads in its strongest orientation. This makes an ideal belay carabiner for new climbers.
Full section top bar for consistent rope handling and increased longevity
A rope running over a full section top bar has more consistent handling characteristics than one running over an I-Beam surface. Our belay carabiners feature full section top bars for greater control rope control. Ropes loading over full section bar also bend less than those loaded over I-Beam surfaces, increasing rope longevity.
Keylock nose eliminates snagging
This carabiner’s nose slots into a groove in the gate, allowing it to achieve full strength without a gate notch. This creates a clean internal profile that won’t catch on gear, bolts or slings, giving easier clipping and removal from systems.
I-Beam construction for optimum strength to weight ratio
I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.
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
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
Yr 2008 ? Day 100 ? Serial Number 1450 ? Machine A
For us, Quality Assurance isn’t so much a process as a way of life. As users ourselves we know that when working at height, one’s safety system has to be up to the task, no if‘s or but’s, compromises or doubts as any failure could have catastrophic consequences. When working in an extreme environment you need to be focused on the job not worrying whether the gates on your connectors are going to stick.
In general, equipment fails as a result of misuse. It’s one thing meeting a standard or ‘norm‘, but quite another to ensure that the ultimate strength of each individual product is at least as high as both it’s rated strength and the requirements of a standard. At DMM we strive to build in sufficient reserves to be sure that each product delivers when put to the ultimate test. We achieve this through stringent controls at each stage of production.
Each operator is highly trained in the use of Statistical Process Control systems and on top of all the routine tests we run 3 sigma rating controls on each batch. Since all safety critical processes are carried out on site we are in a position to take appropriate preventative and corrective action immediately.
We are accredited to ISO:9001/2008. All products are CE certified and many are approved to CSA, ANSI Z359.1(07+09) NFPA, NATO.
Statistical Process Control
The statistical process control system that we have implemented over the years enables us to have absolute control over each individual stage of the production process. We then have a system of ongoing batch testing which monitors and ensures that our product strength is maintained and exceeded. Every machine operator carries out routine checks and measurements to ensure that their operation stays within its pre-defined tolerance levels.
CE Marking and Product Conformance
The CE marking process is known as Type Examination and is an important supplement to our Quality Management System. In line with the requirements of European Union Personal Protective Equipment (PPE) Directive 89/686/EEC all products designed and manufactured by DMM which are classified as PPE are independently type examined and tested to the relevant European Standard for Industrial Safety and Mountaineering. Only after meeting the requirements of the PPE Directive and the relevant European Standard are we allowed to mark 0120CE (the “CE ” mark) on our products.
ISO 9001:2008 compliance and CE marking/product conformance are monitored by CEN (Committee for European normalization. Notified Body No. 0120 (SGS UK Ltd., Weston-Super-Mare, Somerset, UK ). It is a legal requirement that we maintain our Quality Management System as part of the PPE Directive “CE ” marking process.
Statistical Quality Control
DMM were the first company to use a “3 Sigma” Statistical Quality Control (SQC ) technique to establish and monitor the strength ratings marked on products.
Meeting the standards is one thing, but our philosophy at DMM is to continue to improve the strengths of our products to exceed these requirements where possible. Using test data derived from destructive testing samples at the design stage, we can set the rated strength of the product with ‘3 standard deviations’ in reserve. This gives greater security in situations which might not be reflected in the standards but may happen in non-laboratory or misuse conditions.
Batch production means that components stay together throughout the manufacturing process from the moment the raw material is issued from the stores to the moment they pass through to final inspection. This ensures complete traceability from the purchase order for the raw material used through to when the product goes into our finished product stores.
Investors in People
DMM were the first manufacturing company in Wales to be registered to the II P standard (July 1992). In December 2006 we also surpassed all target requirements set out in to the latest version of this important standard. The Investors in People award is, as it’s name suggests, people orientated and its main objectives are:
(a) to develop strategies to improve the performance of the organisation through its people
(b) to ensure that the organisation takes action in order to improve its performance through its people and
(c) to evaluate the impact of this investment in people on the performance of the organisation.
II P is more than just a training system, the II P system is a key mechanism that helps us to target areas for improvement in all aspects of the business.
One of our continuous goals is to reduce our environmental footprint both locally and globally. Our Environmental Policy has been recognised by the Welsh Assembly Government as being the best in Wales for any manufacturer. We are committed to:
- Maintaining 100% recycling of our product
- Reducing our energy consumption
- Reducing emissions from our factory site
- Increasing the recycling of production, administrative and distribution by-products
- Make a positive contribution to sustainable development
