The 200 and 300 series of the Kierr Flex are hinged so that if you want to walk through the door you can open it more easily without removing the door holdback. Using the convenient rotary knobs, you can tighten the door holdbacks securely. You can place the Flex 300 high on your door so that you can easily walk through it yourself without having to open it. In addition, you can fold it so it is easy to store. The rubber protection of the flexible plastic clamps ensures a good fit on plastic, wood and aluminum and even on window frames with rounded or bevelled corners! Use in children&#8217;s rooms is at your own risk because of loose parts. This also applies to outward opening windows in case of falling down.       <\/p>\n<p>&nbsp;<\/p>\n<table class=\"shop_attributes table table-bordered attribute-table table-striped\">\n<thead>\n<tr>\n<th><strong>Property<\/strong><\/th>\n<th><strong>Value<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<th><strong>Min. gap position<\/strong><\/th>\n<td class=\"product_dimensions\">approximately 15 cm<\/td>\n<\/tr>\n<tr>\n<th><strong>Max. gap position<\/strong><\/th>\n<td class=\"product_dimensions\">approximately 50 cm<\/td>\n<\/tr>\n<tr>\n<th><strong>Min. clamping position<\/strong><\/th>\n<td class=\"product_dimensions\">approximately 1 cm<\/td>\n<\/tr>\n<tr>\n<th><strong>Max. clamping position<\/strong><\/th>\n<td class=\"product_dimensions\">approximately 20 cm<\/td>\n<\/tr>\n<tr>\n<th><strong>Dimensions key holder<\/strong><\/th>\n<td class=\"product_dimensions\">Approximately 72 cm long, 3 cm wide (excl. clamping blade) foldable so easy to store<\/td>\n<\/tr>\n<tr>\n<th><strong>Dimensions clamp blades for door<\/strong><\/th>\n<td class=\"product_dimensions\">8 cm wide, 4 cm high<\/td>\n<\/tr>\n<tr>\n<th><strong>Dimensions clamp sheets for frame<\/strong><\/th>\n<td class=\"product_dimensions\">8 cm wide, 4 cm high<\/td>\n<\/tr>\n<tr class=\"alt\">\n<th><strong>Protection frame\/door clamp blades<\/strong><\/th>\n<td>Cellular rubber 2mm<\/td>\n<\/tr>\n<tr>\n<th><strong>Material \/ Color<\/strong><\/th>\n<td>Aluminum and movable plastic clamping blades<\/td>\n<\/tr>\n<tr class=\"alt\">\n<th><strong>Interior style<\/strong><\/th>\n<td>Robust yet elegant<\/td>\n<\/tr>\n<tr>\n<th><strong>What&#8217;s in the package<\/strong><\/th>\n<td>Kierstandhouder complete<\/td>\n<\/tr>\n<tr class=\"alt\">\n<th><strong>Warranty<\/strong><\/th>\n<td>1 year<\/td>\n<\/tr>\n<tr>\n<th><strong>Sold by<\/strong><\/th>\n<td>By piece<\/td>\n<\/tr>\n<tr class=\"alt\">\n<th><strong>Instructional video<\/strong><\/th>\n<td><a href=\"https:\/\/youtu.be\/f3J-bHeeRL0\">https:\/\/youtu.be\/f3J-bHeeRL0<\/a><\/td>\n<\/tr>\n<tr>\n<th><strong>Weight<\/strong><\/th>\n<td>Approximately 400 grams<\/td>\n<\/tr>\n<tr>\n<th><strong>Fix<\/strong><\/th>\n<td>plastic knurled knob<\/td>\n<\/tr>\n<tr class=\"alt\">\n<th><strong>Supplies<\/strong><\/th>\n<td>No<\/td>\n<\/tr>\n<tr>\n<th><strong>Brand<\/strong><\/th>\n<td>Kierr<\/td>\n<\/tr>\n<tr class=\"alt\">\n<th><strong>What is the product suitable for<\/strong><\/th>\n<td>Opening\/locking of doors<\/td>\n<\/tr>\n<tr>\n<th><strong>Applicability of gap holder<\/strong><\/th>\n<td>Inside and outside hinged doors.
