Siman 521
Presented here for study, not as a practical ruling. The Shulchan Aruch rules by Sephardi custom, the Rema's glosses by Ashkenazi custom, and the Kitzur follows Ashkenazi custom. For a practical question, ask your rabbi.
א מַשִׁילִין פֵּרוֹת דֶּרֶךְ אֲרֻבָּה פי' מִן כִּי יִשַּׁל זֵיתֶךְ (דְּבָרִים כח, מ) כְּלוֹמַר מַפִּילִין הַפֵּרוֹת לָאָרֶץ בְּיוֹם טוֹב; וְלֹא יְשַׁלְשְׁלֵם בְּחַלּוֹנוֹת וְלֹא יוֹרִידֵם בְּסֻלָּמוֹת וְלֹא יְטַלְטְלֵם מִגַּג לְגַג, אַף עַל פִּי שֶׁהֵן שָׁוִין.
1 The Law The Law of Moving Fruits from Place to Place on a Holiday, and it has 3 Simanim: 1. We can drop fruits through a trapdoor (meaning, from "when your olives will drop" (Deuteronomy 28:40), as in, when fruits fall to the ground) on a holiday. One should not drop them through windows nor lower them on a ladder nor carry them from roof to roof, even if the two are the same (height).
ב מֻתָּר לְכַסוֹת פֵּרוֹת אוֹ כַּדֵּי יַיִן אוֹ לְבֵנִים, מִפְּנֵי הַדֶּלֶף.
2 It is permitted to cover fruit, wine jugs, or bricks because of water leaking [through the roof].
ג לִתֵּן כְּלִי תַּחַת הַדֶּלֶף, כְּדִינוֹ בְּשַׁבָּת כָּךְ דִּינוֹ בְּיוֹם טוֹב וְעַיֵּן לְעֵיל סִימָן של"ח (סָעִיף ח').
3 Regarding putting a dish under dripping water, the rule on a holiday is the same as the rule on Shabbat (and see above chapter 338 paragraph 8).
