Telescopic wrenches

Telescopic

— telescopic are mainly balloon wrenches (see "Type"), as well as some wrenches with a ratchet-reversing mechanism (see the relevant paragraph) — mainly models with a landing square for interchangeable socket heads. This function means that the wrench handle can be extended during operation. This allows you to achieve high forces on fasteners (due to the large length of the lever) and at the same time provides ease of storage and transportation. On the other hand, a telescopic tool is more expensive than usual and at the same time somewhat less reliable and durable — the connection is a weak point and tends to become loose as it wears.
