After advancing the headrest to its maximum 90\u00b0 forward tilt, pulling it slightly past the top dead-center disengages the internal pawl, allowing the headrest to fold smoothly back down to the 0\u00b0 home position.<\/p>\n<h3>Q2: Can the plug-in rod be separated from the sofa backrest during shipping?<\/h3>\n<p>Yes. The solid rod slides directly into the pre-installed carcass sleeve. This detachable design enables furniture factories to ship headrests detached inside the master carton, significantly reducing export shipping cube volume.<\/p>\n<h3>Q3: What is the wholesale MOQ and production lead time for BLS-135?<\/h3>\n<p>Our standard production MOQ is 500 pairs (1,000 pcs). Standard zinc-plated stock can ship within 7 working days, while customized rod lengths or full 20GP container orders take approximately 20 days.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p style=\"font-size: 15px; line-height: 1.6; color: #1e293b; margin-bottom: 12px;\">Manufactured by BLS Hardware (Zhengkai Hardware Factory, Jinli, Guangdong), our <strong>BLS-135 practical adjustable sofa headrest hinges<\/strong> combine solid cold-drawn carbon steel plug-in rods with matching metal mounting sleeves.
