8 mm (Antrax) Diameter:

The smallest in the resin anchor range and currently the only 8 mm model on the market.

The dimensions are smaller and the surface is a pale matte grey, making it the least visible resin anchor.

-Shank with knurled surface;
-Anchor with the best sealing performance in the resin than the other systems
-Anchor resistance unchanged respect to those of greater diameter
-This anchor also saves on resin as the drill hole must only be 9 mm x 80 mm. (Usually a Ø10 mm hole is used).
-Drilling a 9 mm hole also saves the drill's battery power.
-It is also very cost-effective.

10 mm (Superstar) Diameter:

It is undoubtedly the most commonly used resin anchor in the world.

The shape of the eyelet has been designed to withstand high levels of tensile or shear force.

-The shank is knurled; 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 anchor's eyelet can easily accommodate two carabiners simultaneously or a Ø10 mm folded and flattened rope.
-The “SUPERSTAR” anchor's eyelet is perfectly smooth, allowing top-rope lower-offs without damaging the rope sheath.
-Like all our climbing anchor systems, the “SUPERSTAR”’s surface is matte grey to minimize environmental and visual impact.

12 mm (Masterfix) Diameter:

Strong and secure stainless steel resin anchor designed for placing quickdraws and building belays on mountaineering and climbing routes.

Ideal for use on soft rock, sandstone or similar.

The wide diameter and extended length of the shank makes this bolt entirely reliable.
