# Baby gates for wooden banisters and newel posts

Which baby gates can be fitted to a wooden banister or newel post?

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\. Each adapter is designed for one banister, for a banister on one side and a wall on the other\. Qdos Pressure Mount Y\-Spindles: The Y\-spindles are an adapter that lets a Qdos pressure\-mount gate be fitted where round banisters or spindles are present instead of a flat surface\. The maker states the Y\-spindles were designed and tested only for Qdos pressure\-mount gates, so they are not for other brands' gates\. Qdos Spectrum Designer Pressure Mount Baby Gate: For a wooden banister at the bottom of stairs, the Universal Stair Mounting Kit is likely needed\. The manual warns that children have died or been seriously injured when gates are not securely installed\.

Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live\.

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.
