Description
Description
Notch SafeBloc is a revolutionary rigging tool that increases safety by adding controlled friction to the rigging system at the top of the tree. It reduces the load on the anchor point and facilitates assisted lowering for increased efficiency.[2][7]
The SafeBloc can be used in all configurations where a block or pulley is normally used for rigging. By threading the rope through one, two or all three holes, you can adjust the friction level as needed – maximum friction through all three holes. The tool is ideal for small to medium loads without the need for basal lowering friction, while larger loads require an additional brake.[2][3][7]
Made in the USA with a lifetime warranty. The SafeBloc has no moving parts, is light and durable with a hard-anodised finish for extremely long service life.[2][7]
Features
- Revolutionary design that adds friction for increased safety and reduced load on the anchor point
- Adjustable friction through 1–3 holes (max friction in all three)
- No moving parts – minimal maintenance and high durability
- Hard-anodised for long service life and resistance to wear
- Lightweight for easy handling in the tree crown
- Works without basal lowering friction for small-to-medium loads
- Facilitates the climber's assisted lowering after the initial drop
- Lifetime warranty from Notch Equipment
Technical specifications
- Weight: 1.1 kg (2.25 lb)[3][7]
- Working load limit (WLL): 2700 lbs (approx. 12 kN)[7]
- Inner hole diameter: 38 mm (1.49 in / 1.5 in)[2][3][7]
- Rope capacity: Max 24 mm (3/4 in)[2][3]
- Outer groove: 0.94 in (approx. 24 mm rope)[2]
- Dimensions: 9.5 x 3.5 x 1.5 in (approx. 241 x 89 x 38 mm)[7]
- Height: 40 mm (1.57 in)[3]
- Material: Hard-anodised aluminium alloy
- Country of manufacture: USA[2][7]
Safety video: See the SafeBloc in action HERE
Note: For medium and larger loads, combine with basal lowering friction. Choose the friction level before use.
