A method for installing a drawer element, having the following steps: - fixing a first pullout guide on a first side wall and fixing a second pullout guide on a second side wall, which is opposite to the first side wall; - installing a device for synchronizing the movement of the movable rails of the two pullout guides , wherein a holder having at least one deflection element is plugged or latched onto each pullout guide ; ∘ wherein an abutment web of a housing of the holder is positioned with two protruding hooks at openings of a middle rail of the first or second pullout guide , wherein first the rear hook is inserted into the first opening and then the front hook is inserted into the second opening , and whereby the hooks are formed as latching hooks enabling a the holder to be pivoted and locked to the middle rail without the use of tools, ∘ or ∘ the holder comprises a mounting section for fixing to hooks at a middle rail of the first or second pullout guide , said mounting section comprising U-shaped receptacles into each of which a hook is inserted; - laying a cable pull around a deflection roller provided on the pullout guide ; - coupling at least one rail of each pullout guide via a connecting device to the pullout guide , and - setting the tension of the cable pull via a device for setting the cable tension. - fixing a first pullout guide on a first side wall and fixing a second pullout guide on a second side wall, which is opposite to the first side wall; - installing a device for synchronizing the movement of the movable rails of the two pullout guides , wherein a holder having at least one deflection element is plugged or latched onto each pullout guide ; ∘ wherein an abutment web of a housing of the holder is positioned with two protruding hooks at openings of a middle rail of the first or second pullout guide , wherein first the rear hook is inserted into the first opening and then the front hook is inserted into the second opening , and whereby the hooks are formed as latching hooks enabling a the holder to be pivoted and locked to the middle rail without the use of tools, ∘ or ∘ the holder comprises a mounting section for fixing to hooks at a middle rail of the first or second pullout guide , said mounting section comprising U-shaped receptacles into each of which a hook is inserted; ∘ wherein an abutment web of a housing of the holder is positioned with two protruding hooks at openings of a middle rail of the first or second pullout guide , wherein first the rear hook is inserted into the first opening and then the front hook is inserted into the second opening , and whereby the hooks are formed as latching hooks enabling a the holder to be pivoted and locked to the middle rail without the use of tools, ∘ or ∘ the holder comprises a mounting section for fixing to hooks at a middle rail of the first or second pullout guide , said mounting section comprising U-shaped receptacles into each of which a hook is inserted; - laying a cable pull around a deflection roller provided on the pullout guide ; - coupling at least one rail of each pullout guide via a connecting device to the pullout guide , and - setting the tension of the cable pull via a device for setting the cable tension. <EOS>
