    Get greater reliability and longevity from your equipment. We provide a 3 year warranty on non-wearing parts.
  2. Onsite maintenance and annual inspection
    Inspection can be done locally as part of your normal annual course inspection process. Many repairs are extremely simple and can be done in the field as well.
  3. Reduced annual inspection costs
    With annual third party inspection handled onsite by a qualified PPE inspector, there is minimal out of service time and no shipping costs.

How does it work?

It’s simple. The “key” to locking and unlocking the LockD Clips smart belay system is the Tweezle Key. When a LockD Clip is inserted onto a Tweezle Key (mounted on a lifeline), it locks, while the other clip unlocks.

Using the Tweezle Key ensures that climbers only clip onto lifelines intended for participant use, eliminating the risk of customers clipping onto other lines not designed for participants.

What’s an integrated carabiner system?

Also known as a smart belay system, an integrated carabiner system such as LockD Clips is considered a type of continuous belay system used by adventure park operators as a safety system for keeping climbers attached to the lifelines throughout the course.

A smart belay system consists of a dual-lanyard, dual clip design in which one clip is always locked when the other is open.  This type of system allows for active engagement with the equipment by the climber but ultimately ensures that the climber is attached to the lifeline at all times.  Smart belay systems, such as LockD Clips, also allow the climber to choose different trails, pass slower climbers and engage with vertical as well as horizontal elements, providing greater control and flexibility in the activity.

Other types of systems

A continuous belay system – generally a roller or trolley that follows a set path – ensures that the climber is attached to the lifeline, but the climber lacks engagement with the course and their equipment, providing a more passive experience.  The continuous belay system also prevents climbers from passing each other, creating bottlenecks that can negatively impact the climber experience.  Other self-belay system mimics the active engagement of the LockD Clip system but without the safety component, introducing a high level of risk into the activity.
