This method is used for removing gear from a sport anchor, with a subsequent lowering of the lead climber. An alternative is to [[abseiling|abseil]] from an anchor. For routes with no fixed protection at the anchor point (trad), you have either to leave some gear behind, or where it is appropriate and reasonably safe, use for example abseil with an equivocation hitch.

=== Lowering directly from bolts or fixed ring ===
This method is forbidden by climbing associations in some countries and places. The ban is due to an increased bolts and fixed rings abrasion which leads to unnecessary and undesired shortening of the material replacement cycles. For example at traditional sandstone routes which are (due to a tradition) almost exclusively equipped with fixed rings, it would mean additional drilling into a rock which is often protected by a law due to nature preservation for further generations. In addition, this method cannot be used for lowering directly from hanger plates as the friction over the plates edges would severely damage the rope.

=== Lowering from a pre-built sport anchor - quick method ===
See the separate page with the [[Lowering_from_a_pre-built_sport_anchor_-_quick_method|quick method description]].
 
=== Lowering from bolts with maillons ===
Lowering from maillons is analogous to the [[#Lowering from a pre-built sport anchor|lowering from a pre-built sport anchor]], except that you thread the rope through the maillons instead of the rappel ring. To ensure redundancy, you must thread the rope through both maillons, as there is no chain connecting the bolts. The quick method can be used only if the maillons are big enough, othewise it quickly becomes cumbersome.
 
{{#invoke:FlexGallery|gallery

|File: lowering_maillons_step1.png
|Thread the rope through the maillons. Both maillons should be threaded in the same way - either in->out, or out->in
|File: lowering_maillons_step2.png
|Once the maillons are threaded, you continue as in the [[#Lowering from a pre-built sport anchor|method with the rappel ring]] by [[Figure_eight#Follow-through_(tie-in_on_the_rope_end)|tying in by a Figure 8]], the rest of the steps is analogous

=== Lowering directly from bolts or fixed ring ===
This method is '''forbidden by climbing associations in some countries and places'''.<ref>For example the czech mountaineering association allows abseiling exclusively. For toprope, it explicitly orders to place carabiners into the fixed protection (Article 3, number 4): {{cite web | url=https://www.horosvaz.cz/res/archive/330/056388.pdf | title=Pravidla lezení ve skalních oblastech ČR | publisher=Český horolezecký svaz | author1=Výkonný výbor ČHS | website=horosvaz.cz | date=June 12, 2020 | access-date=1 November 2025}}</ref> The ban is due to an increased bolts and fixed rings abrasion which leads to unnecessary and undesired shortening of the material replacement cycles. For example at traditional sandstone routes which are (due to a tradition) almost exclusively equipped with fixed rings, it would mean additional drilling into a rock which is often protected by a law due to nature preservation for further generations.<ref>{{cite web | url=https://horolezeckametodika.cz/horni-jisteni | title=Horní jištění | publisher=HOROLEZECKÁ METODIKA | first1=Tomáš | last1=Kublák | website=Horolezeckametodika.cz | access-date=1 November 2025 | url-status=live | archive-url=https://web.archive.org/web/20240305142706/https://horolezeckametodika.cz/horni-jisteni | archive-date=5 March 2024}}</ref> In addition, this method cannot be used for lowering directly from hanger plates as the friction over the plates edges would severely damage the rope.
 
The method is very similar to the method with maillons, only the rope is in this case threaded directly through the bolts.
