Unlike conventional compression gas springs, this unit operates in <strong>traction (tension)<\/strong>, generating a pulling force of <strong>250 N<\/strong> that makes it the ideal solution wherever a controlled, sustained retracting effort is required \u2014 such as on flush hatches, retractable panels, sliding doors, or integrated furniture mechanisms aboard sailing and motor yachts.<\/p>\n<p>Built to withstand the rigours of the marine world, the strut is equipped at both ends with <strong>EF-BS009X ball sockets<\/strong>: 10 mm ball sockets machined from <strong>316 grade stainless steel<\/strong>, the most corrosion-resistant stainless alloy available for offshore use. The M8 x 1.25 threaded connection ensures a secure, vibration-proof attachment to the host structure, whether that is a fibreglass hull liner, teak joinery panel, or aluminium deck fitting.<\/p>\n<p>With a <strong>closed length of 387 mm<\/strong> and a <strong>fully extended length of 637 mm<\/strong>, the strut delivers a usable stroke of 250 mm, providing generous travel for larger hatches and access panels. The body carries the standard marine pressure warning label (<em>HAUTE PRESSION \u2013 NE PAS OUVRIR\/PERCER\/CHAUFFER<\/em>), confirming that this gas spring is a sealed, pressurised unit that must never be drilled, cut open, or subjected to heat. The reference label reads <strong>155176 \u2013 250 N<\/strong>, allowing straightforward identification for maintenance and reordering purposes.<\/p>\n<p>This component is distributed in France by <strong>Ressorts SPEC<\/strong> and is available as a spare part for original-fit installations on production vessels as well as for custom refit and new-build projects requiring a reliable traction solution.<\/p>\n<h3>Specifications<\/h3>\n<ul>\n<li><strong>Reference:<\/strong> 155176 \u2013 Rev.

Its <strong>316 stainless steel ball sockets<\/strong>, correct force rating, and OEM pedigree make it a direct, reliable replacement for the original-fit part. Before purchasing, confirm that your application genuinely requires a <strong>traction<\/strong> (tension) spring rather than a conventional compression unit, and verify that 250 N is the appropriate force for your hatch or panel weight and geometry. If both conditions are met, this strut is an excellent, ready-to-fit choice.<\/p>\n<\/div>\n<div data-class=\"product-pros_cons product-good-to-know\">\n<h3>Good to Know<\/h3>\n<ul data-class=\"pros-cons-list\">\n<li>This is a <strong>traction (tension) gas strut<\/strong> \u2014 it works by pulling, not pushing.
