Raumer “FORK" Stainless Steel Ø10x80
Canyoning specific anchor.
Designed to deliver high performance in tensile and shear strength.
Composed of two parallel knurled shanks, this anchor excels in practicality, usability and safety.
- The two shanks are knurled with a cross-hatch covering 50 mm
- This method of resin fixing has long been the most reliable and resistant, particularly when compared with resin anchors with transversal grooves or horizontal dimpled surfaces which are notoriously unreliable and dangerous.
- The shape of the eyelet has been designed to withstand high levels of tensile or shear force and to withstand serious strain caused by flooded mountain streams.
- The “FORK” anchor's eyelet is perfectly smooth, allowing top-rope lower-offs without damaging the rope sheath.
- Like all our climbing anchor systems, the surface is matt grey to minimise environmental and visual impact.
From 2013 the material used in the majority of our anchors is now stainless steel AISI 316L, which offers a higher resistance to marine corrosion than the former AISI 304.
To highlight this change each article is stamped with the relevant symbols.
There is also a “Marina” version of this anchor which is highly resistant to saline corrosion.
To mark the difference between stainless steel AISI 316L and the marina version of the same material, all marine-suitable anchors have been marked with a fish symbol and the initials “INOX".
We recommend reading the attached PDF document for a detailed explanation of the problems presented by marine corrosion.

Installation of FORK RAUMER resin anchors
See the attached technical sheet.
Placement is simple, fast and effective when using our exclusive "dima" tool (Art.532).
Placing anchors using a resin glue is a simple but delicate process.
If not executed correctly, resistance to tensile and shear force can be seriously compromised.
For this anchor we recommend using a bicomponent epoxy resin injection method.
- Choose an undamaged and solid area of rock away from edges.
- Strike the surface with a hammer to determine the rock consistency.
- Drill the first hole perpendicular to the placement surface. (Please note: the hole must be 2mm wider than the shank diameter). The depth should be no more than 5mm longer than the anchor shank. This is to avoid wasting excess resin. DO NOT make a lengthwise groove as this is ineffectual with this type of anchor. If anything, flare the lower side of the first hold slightly to facilitate insertion of the anchor shank. To ensure the second hole for the upper shank is exactly in line with the gap between shanks we recommend using the special “dima” tool (Art.532). Proceed as follows: Insert the guide shank of the dima (Ø 12mm) into the first hole. Turn the shank into the position of the chosen second hole then insert the drill bit. Keep the drill in line with the guide hole and make the second hole until nearing (but not touching) the dima’s tube. Extract the drill, remove the dima from the first hole then continue drilling the upper hole until reaching the correct depth.
- Clean both holes well, either with an appropriate pump or by blowing down a rubber tube. A pipe-cleaner is also recommended to completely remove any dust from inside the holes.
- Using an injector gun insert the correct dose of resin into each hole.
- Insert the anchor slowly to a point about 1cm from the base and move it back and forth to coat the surface of the two shanks completely in resin. Now insert the “FORK” fully. A small amount of resin may exit from the hole edges and around the eye, demonstrating a good fit. Use latex gloves throughout this procedure. Remove any excess resin from the edges of the eyelet, sealing the edges. This is important to prevent water from entering in the future. This is particularly important in marine environments.
- When using this anchor to protect overhangs or roofs, use the same process as for the previous anchors (art.160 etc) but do not create the groove. Once the anchor is in place, hold it in position using a couple of cocktail sticks (or similar…) between the edge of the hole and the shank's surface. Without this the anchor has a tendency to fall out of the vertical hole. Once the resin has hardened the two sticks can be easily removed.
- After applying the resin do not touch the anchor. Leave to set for at least 24 hours – if possible for 2/3 days, depending on ambient temperature. Respect any advice given by the resin's manufacturer.
