Toyjolka Baby Gate Banister Adapter — 2-Piece Stair Post Fitting Kit for Round or Square Posts

Smart safety, simple fit

The Toyjolka Baby Gate Banister Adapter is a compact, two‑piece kit designed to help you mount a stair gate against posts without drilling or wall damage. It focuses on the posts themselves, delivering a sturdy anchor that adapts to common post shapes. Note that the gate itself is not included, so you can pair this kit with your existing gate hardware after you confirm compatibility.

Before you purchase, measure your gate and posts. This kit uses longer bolts to simplify alignment, and its design aims to support a clean, secure setup that blends into home surfaces while you’re juggling a busy household. Use this adapter as a dependable option for stair cases where a traditional mounting approach isn’t feasible.

• Round posts: 1.96" to 3.93" in diameter (5 cm to 10 cm)
• Square posts: 2.36" to 3.93" wide (6 cm to 10 cm)
• Gate not included in the package

What’s built to last

• Durable ABS body paired with steel and rubber components for long‑term use
• Extra-long 3.9" (10 cm) bolts to help you align quickly and securely
• Includes 4 screws for stable mounting and peace of mind
• Rubber head pad protects furniture and finishes from scratches

Design and fit

The shaped shaft design provides a secure fit on varied post profiles, while the rubber pad cushions contact surfaces. This combination helps fix the adapter more firmly and reduces potential scuffs on your staircase furniture.

Installation made simple

Installers can complete the setup with a standard screwdriver. The kit is designed to be fast for two people to assemble together, and the process is non‑invasive, without wall damage. If you want extra confidence, there is a video guide available to walk you through the steps before you start.

Usage notes

Important reminder: measure your gate size before purchasing. This kit is intended to work with compatible gates and posts, and it does not replace or include a gate itself. Consider this adapter as a practical way to adapt an existing gate to your stairs.
