Perforated Sleeve for Hollow Block Masonry / Hollow Brick Measurements: 20 x 85 mm
If you fix climbing holds to masonry, you have to distinguish the following:
Variation 1) Hollow block masonry/ hollow brick
For fixing in a hollow block masonry/hollow brick you need a perforated sleeve for the internally threaded sleeve. You also need a tube of injection adhesive, with technical approval, of course. One tube of injection adhesive is enough for about 5 - 7 hole, to say fixing points for climbing holds. A detailed mounting instruction comes with the injection adhesive.
Variation 2) Solid brick
Solid brick is a brick without vent holes. In this case you do not need perforated sleeves, but only the internally threaded sleves and injection adhesive with technical approval. A tube of injection adhesive is enough for about 10 - 12 holes, to say fixing points for climbing holds. A detailed mounting instruction comes with the injection adhesive.
