Summary. We examine a categorial construction which permit to obtained a new re ective subcategories with a specal properties. Key words: Re ective subcategories, the pairs of conjugated subcategories, the right product of the two subcategories. Results. Let K be a core ective subcategory, and R a re ective subcategory of the category of locally convex topological vector Hausdor spaces C2V with respective functors k : C2V -! K and r : C2V -! R. Concerning of the terminology and notation see [1]. Note by K = fm 2Mono j k(m) 2 Isog, "R = fe 2 Epi j r(e) 2 Isog. Further for an arbitrary object X of the category C2V we examine the follows construction: let kX : kX -! X is K-coreplique, and rkX : kX -! rkX-replique of the respective objects. On the morphism kX and rkX we construct the cocartesian square vX  kX = uX  rkX:
