The Cal-Royal VT51 Vinyl Threshold is a commercial-grade center section threshold measuring 1 1/2" H x 5 1/2" W, engineered specifically for use as a connecting center piece between other Cal-Royal threshold components. This vinyl threshold is designed to be installed as a center section for two pieces of VT38, or a combination of one VT38 and one VT49, allowing for extended threshold configurations across wider door openings. Built for commercial door applications, the VT51 provides a reliable transition solution as part of a modular threshold system.

Cal-Royal VT5136-BL – Frequently Asked Questions

1) Do I need to order anything else with the Cal-Royal VT51?
Yes. The VT51 on its own does not make a complete sill. It's the middle piece, so you also need either two VT38 sections or one VT38 plus one VT49 to finish the assembly. Order the outer pieces in a matching length and finish so the run is continuous.
2) What lengths does the Cal-Royal VT51 threshold center section come in?
Three lengths: 36, 48 and 73 inches. The 36 inch covers a standard single leaf, 48 suits a wider single opening, and 73 inches is the one to order for a pair of doors so the assembly runs unbroken across both leaves.
3) Will the vinyl VT51 hold up the way a metal threshold accessory would?
The VT51 is vinyl throughout, which is why it belongs to Cal-Royal's vinyl threshold system rather than an aluminum or steel sill line. If your spec calls for a metal transition piece instead, the Pemko 61 Series interlocking J hook threshold accessory is a steel-constructed 36 inch option in the same threshold family of parts.
4) Is the VT51 threshold rated for commercial traffic or is it a residential part?
It's a commercial item. Cal-Royal classes the VT51 as commercial door hardware, and the modular sill system it belongs to is built for office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities.
5) Can I cut a 73 inch VT51 down to fit a narrower opening?
Order by the closest length rather than planning to modify. Cal-Royal supplies the VT51 in 36, 48 and 73 inch, and the whole point of the modular system is that you set total coverage by combining the center section with VT38 or VT49 pieces rather than by trimming.
