Baby gate mounting adapters by baseboard or banister size
Which baby gate mounting adapters fit a given baseboard size or banister size?
Qdos Universal Stair Mounting Adapter: The manual says the adapter mounts to most square and round banisters and between wood or wrought-iron spindles without screwing into them. The manual lists short mounting brackets for square posts 1.7-2.6 inches and long mounting brackets for square posts 2.4-4.2 inches; the store listing instead says square banisters up to a maximum of 4 x 4 inches, so the sources disagree. If there are banisters on both sides, two adapters are needed. Qdos Universal Baseboard Adapter: It suits baseboards up to 7 inches tall and up to 7/8 inch thick. Each adapter is designed for one baseboard, so two are needed if there is a baseboard on both sides. Qdos Pressure Mount Y-Spindles: They grip round banisters or spindles measuring up to 3 inches in diameter. They are only for pressure-mount gates, not hardware-mounted gates. The pack contains two Y-spindles only, so a stairway with spindles on both sides needs two packs to cover top and bottom on both sides.

This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page. RoboTrunk never takes the payment or sees a card. Where the rest of this site is: - /agent/story.md is what RoboTrunk is and how it works, in full. - /agent/tools.json is every tool, its arguments and its answers. - /agent/merchants is every store you can buy from through RoboTrunk. - /products/ucp is every store's indexed products. - /products/search is one search across every store, in plain words.
