Shop Outdoor Rock climbing and mountaineering Climbing equipment Ascenders

Ascender is a specialized device used in mountaineering, caving and other vertical activities to aid in rope ascent. It is designed to securely fix the rope in one direction and at the same time allow smooth movement along the rope in the opposite direction. Here are some factors to consider when choosing a climbing block:

Mechanism type: Ascenders typically use either a toothed cam or a spring-loaded cam mechanism. Geared cams provide a more secure grip on the rope, but can cause more wear, especially on softer ropes. Spring cams may be gentler on the rope, but may be less secure in certain situations.
Compatibility with rope diameters: Ascenders are designed to work with certain rope diameters. Make sure the ascender you choose is compatible with the diameter of the rope you plan to use. Check the manufacturer's recommendations for the rope size range.
Ease of use: Look for an ascender that is easy to use. Look for features like ergonomic handles, smooth cam engagement. A comfortable and easy-to-use ascender can make a significant difference during long ascents.
Weight: Aluminium and alloy are common choices for a combination of strength and light weight. Consider the weight of the blocker, especially if you are going to wear it on longer ascents.
Certificates: Check if the ascender has the appropriate certificates from security standards organizations. Certificates indicate that the device has passed testing and meets specific safety requirements.

By considering these factors, you will choose a light, safe and simple ascender. Always follow the manufacturer's instructions and recommendations for proper use and maintenance of the climbing ascender.
