If you have any doubt about the integrity of any DMM product then you should stop using it immediately.
Regular inspection and servicing of your kit is essential as this will highlight any possible problems (see the product user instruction leaflet for more information). In the event of finding a fault, damage, or if you are unsure about a product you should stop using it immediately and contact us.
When goods are returned to us we will carry out a full investigation through our Quality System and inform you of the outcome. To return goods for inspection complete the Return form and send it to us along with the product(s).
We offer servicing for DMM Cams, and will re-sling Torque Nuts if they pass a quality inspection. Prior to sending them to us, we ask you to inspect and assess your gear in accordance to the supplied user instructions and inspection criteria. These are also available as PDF’s on the product pages of our website. If you feel that your gear has more service to give, follow the steps here:
To return Cams for servicing, please complete the Cam Servicing form and include it with the returned item(s).
To return Torque Nuts for re-slinging, complete the Re-sling form and include it with the returned item(s).
We will then carry out our own inspection, and if the item passes, service the equipment and return the item to you as soon as possible. We will send you an invoice via email when the service is complete.
Please note we can only offer this service/re-sling for DMM products.
NB. We endeavour to carry out this service ASAP but during busy times this may take up to 4 weeks. Please allow plenty of time for this service and plan well in advance of your next climbing trip.
Pricing for repairs/servicing
We no longer offer a re-sling service on Mambas.
We are very pleased to have a ‘Partner in Climb’ in the USA. Mountain Tools in California will re-sling any DMM Cams or Torque Nuts. Their service page has the full details: Mountain Tools (mtntools.com). Mountain Tools offer a re-sling service only. They will not perform a safety inspection on the product. If you are in any doubt of the integrity of your DMM products you should stop using it immediately, ask a competent person to check them or contact us for advice at firstname.lastname@example.org.
Full details about inspection and maintenance of all DMM products are included in the user instructions supplied with every product, copies can be found on the relevant product pages on our website.
