The S-5-KHD clamp stands for Klip-Rib® Heavy Duty. Designed mainly for new construction, but can be retrofitted for some applications. The most heavy-duty and durable clamp in the S-5! family, the KHD fits the very distinctive KlipLok / Klip-Rib profiles of Lysaght Klip-Lok® 406 / McElroy Metal Mirage / AEP Span Klip-Rib® / Metal Sales Clip-Loc and similar concealed-fix profiles.
The S-5-T Mini is a medium-duty, non-penetrating seam clamp specifically designed for profiles featuring a "T"-shaped seam configuration. It is a bit shorter than the S-5-T and has one setscrew rather than two.
The S-5-Z Mini clamp is a medium-duty, non-penetrating seam clamp specially developed to fit profiles having a round “bulb” seam configuration. The Mini clamp is a bit shorter than the S-5-Z and has one setscrew rather than two.
