I will certainly be using Surelock for the ends of the slab, but I'm concerned about the gripping of the jack to the strand for stressing. Have you ever seen any attachments to fit desired strand diameters added to these hollow jacks?

Stressing Method | Prestressed Concrete | Civil Engineering

Prestressed concrete is a concrete construction material which is placed under compression prior to it supporting any applied loads (i.e. it is "pre" stressed).[1][2]:3–5 A more technical definition is "Structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads."

Slabs may be reinforced or prestressed and are designed as ribbed slabs. The hollow cores afford a reduction in self-weight of 30% or more, compared with a solid slab of the same depth. For most applications, no propping is necessary during construction, but crane access is essential.

Prestressed concrete is used, for example, in bridge construction, in container construction, in building construction for hollow core slabs or precast prestressed floor units. The correct pre-tensioning is relevant to safety and absolutely necessary for achieving the load capacity of the respective concrete element as planned.
