m-Struts®, standard type (Mechanically Powered Struts), act like a standard gas strut but have no seals to fail or gas & oil to leak. These struts offer robust compression performance in extreme temperature (hot & cold) as well as caustic chemicals (gas & liquid). Universal Stop Tube can be paired with matching struts to provide secure locking in the extended position. End fittings are not installed on m-Struts so be sure to select a matching end fitting, threads are as indicated in the data table. Material construction is as indicated in the data table. Steel external construction models have Nitride protection and are completely black in appearance. Stainless steel models have a plain finish and offer greater corrosion protection.

If you have an OEM or aftermarket application for a Mechanical Strut or other complete functional sub-assembly see our custom engineered & manufactured solutions.
