Fulton & Bray FB319 Quality Roller Sash Window Stop Restrictor for Child Safety and Security - With Key Included (Extra Key)

**** The Fulton & Bray FB319 Quality Roller Sash Window Stop Restrictor emerges as a practical solution for enhancing child safety and adding security to sash windows. Aimed primarily at homeowners concerned about safety, these window stops are reported to be robust, with many users praising the high quality of the included keys and the overall sturdiness of the product. However, installation appears to be an area of contention among customers. While some describe the installation process as flexible and straightforward, others express significant frustration over the lack of fitting instructions. The ambiguity regarding the correct size of drill bits caused confusion, with varying recommendations for drill sizes leading to annoying adjustments during setup. It is worth noting that while some users have found success with a 10mm drill bit, the absence of clear guidelines and the need for modification on the screw threads detracted from the overall experience for several customers. Despite these installation hurdles, many users emphasize that once fitted correctly, the restrictors operate effectively. The ability to adjust the opening of windows for ventilation while still providing security is a highlighted advantage, reinforcing the product’s functionality. Additionally, the aesthetic appeal of the satin chrome finish has resonated positively with users who appreciate a cohesive look in their home fittings. Ultimately, the Fulton & Bray FB319 roller sash window stop restrictors are well-received for their practicality and design, though potential buyers should be prepared for possible installation challenges due to the lack of instructions and the need for specific tools. **
