Softness and Denting<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Aluminium is softer than steel. Dropping a heavy tool on an aluminium rail can dent it. Deep dents weaken the structure and may prevent telescoping.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Solution:<\/strong> Handle with care. Inspect for dents before each use. Do not use a ladder with bent or dented rails.<\/p><div class=\"pai-ad\" style=\"min-height:250px;visibility:hidden;\"><span style=\"display: block; text-align: center; font-size: 10px; margin: 0 0 10px 0; color: #999999;\">Ads<\/span>\r\n<!-- Display-300x250-1 -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:inline-block;width:300px;height:250px\"\r\n     data-ad-client=\"ca-pub-3838168351244230\"\r\n     data-ad-slot=\"9933646018\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">3.
