These instructions explain installation and usage techniques for your STAL equipment. Identified within these instructions are certain techniques and hazards however it is impossible to describe all dangers or possible hazards, if in doubt please contact STAL Anchors for updates and / or additional information.

1. Definition of equipment

Bolt on top protection point for artificial climbing structures as defined in BS/EN 12572-1: 2007

For single-person or multi-person use (200kg Max.).

Do not use this equipment for hauling.

This equipment’s load limits must not be exceeded, nor be used for any purpose other than that for which it is designed.

2. Component identification

(1) Puck, (2) Chain [PSTP or SSTP], (3) Equalisation Link, (4) Connectors

3. Materials

  1. Polyurethane
  2. PSTP – BS/EN 818-3 M10 Plated, SSTP – BS/EN 818-3 M10 AISI 316
  3. SSTP – M7 Stainless Quick Link Connector, PSTP – M8 Mild Steel Quick Link Connector
  4. Connector to be compliant with EN 362 / EN 12275 (2 per unit configured on bottom link of each section of chain – to be used as per connector’s manufacturers guidance).

4. Inspection

A detailed and recorded inspection by a competent person at least once every 6 months is recommended, however this may need to be increased in frequency depending on current regulations in your country or your conditions of usage (i.e. high usage, sea environment, outdoors). An inspection to verify the condition of attachment bolts is recommended at 10 year intervals from the installation date. Pre-use and continual checks are required to ensure the continued safe use of the equipment.

  • Record the results of your inspection, including: manufacturer, model, unique
    identification number, purchase/first use date, next inspection date and relevant
    information: inspector name, comments, inspection results.
  • Before and during each use, check the condition and position of each of the
    components of the anchor to ensure they are actable for use and aligned correctly.
  • The equipment must pass visual and tactile inspection which will consider the
    following: security, mechanical function, surface degradation, wear, corrosion,
    deformation, cracks, burrs, presence of sharp edges.
  • For specific guidance of installed connectors, please refer to the manufacturer’s
    recommendations on all aspect of care, use and maintenance.
  • Equipment which does not pass an inspection or check should be removed from
    possible use.

5. Maintenance, servicing and storage

When cleaning the anchor, only warm water is to be used (25°C Max.), wipe any excess and air dry. Light lubrication of the chain and connectors, using a suitable lubricating oil (as per the connector manufacturers guidance) may be completed.

Modifications, repairs or alterations to the equipment are not permitted, unless authorised in writing from STAL Anchors.

This product must be stored in a clean dry environment, out of sunlight and in a
temperature range of 0°C to +30°C.

This equipment may be damaged if exposed to a corrosive environment or chemicals.

6. Lifespan

There is no maximum lifespan of this product.
Lifespan may be reduced to as little as one use if used in an extreme environment or
subjected to loads outside the stated limits, a visual and tactile check must be passed before each use. This equipment must be removed from use if:

  • Forces outside the stated limits are suspected (major fall or misuse).
  • It fails a check or inspection.
  • Its history is unknown.
  • It becomes obsolete due to changes in applicable standards, regulations, legislation,
    development of new techniques, incompatibility with other equipment…

7. European Standards Examination

SATRA Wyndham Way Kettering, NN16 8SD

8. Equipment Marking

Each Puck is marked with: EN Standards tested to, the Manufacturer Logo (STAL)
Each Chain section is marked with: A. minimum breaking load (30kn), B. batch year C. Batch day, D. model ID, E. Part ID (Note: this may be after the Batch day)

9. 3-year guarantee

This product is guaranteed against any material or manufacturing defect excluding: normal wear and tear, oxidation, corrosion, modification or alteration, incorrect storage or usage, poor maintenance, negligence, uses for which this product was not designed, over tightening. Note: the puck may fade in colour if in direct sunlight, this will not affect the strength of the anchor.

10. Compatibility

For installation in an environment subject to stress corrosion, use only SSTP model anchors with 316 grade stainless attachment hardware.
M10 or M12 hardware may be used to attach the anchor units to the ACS (artificial climbing structure) – this is to be in accordance with the structural calculations provided by the manufacturer (both in positon and type), however STAL Anchors recommended that Nylock nuts be used on all anchor connections and the grade of bolt be a minimum of 12.9 for M10 and 8.8 for M12 components. STAL Anchors will not accept responsibility for use of substandard materials or deviations from approved structural designs when installing the anchors.
Warning: do not combine bolts, nuts, washers or hangers of dissimilar metals.

11. Installing the anchor

This equipment to be installed into artificial climbing structures as defined by BS/EN 12572-1: 2007 ONLY. Before installation, verify that the Anchor and its means of attachment to the supporting medium (e.g. bolt) are made of the same material.

a. Push the bolt through the Puck and Chain (the bolt head sits in the counter sunk recess) into the hole as provided (ensure all components are attached in the relevant sub-structure as approved by the engineering calculations) and tighten the nut / bolt to 25NM following the bolt manufacturers guidance for thread protrusion. WARNING: The bolt MUST be installed through the top chain link
b. After each installation, verify that the chains move freely and are not twisted.
Removal: Unscrew the nut and bolt and remove the anchor. Before reusing the anchor, carry out a detailed inspection of it.

12. Rope Placement

  • The rope MUST be equipped through both connectors only – it is NOT actable to run the rope through the chain – this may result in severe damage to the rope.
  • Direction of Load
    The anchor must be positioned so that the direction of load is equalised between the two chains and is below the Chain ports – angle of load must be under 90°
