SES OPTDF1 Designer Frame for TEC1 HF and TEC1A Telephone Entry
The SES OPTDF1 designer frame is an architectural trim accessory used to improve the finished appearance of select Select Engineered Systems telephone entry panels. It is commonly associated with TEC1 HF and TEC1A installations where the entry station is visible to residents, visitors, or commercial tenants.
Unlike a basic flush ring, a designer frame is selected partly for appearance and partly for fitment. It helps create a cleaner border around the entry unit, but it still must match the faceplate size, hands-free style, and mounting arrangement of the installed SES system.
OPTDF1 should not be confused with OPTDF2, FLR, FLRT1, or other SES mounting accessories. Public references include TEC1 HF, TEC1A, and some CAT/TEC-style mentions, so the safest approach is to verify the installed model and frame dimensions before ordering.

Technician Note
Do not select a designer frame by brand alone. SES frame fitment depends on the telephone entry model, display style, hands-free style, and cutout.
Before Ordering
- Confirm the unit is TEC1 HF, TEC1A, or another model that specifically uses OPTDF1.
- Compare the required frame to OPTDF2, FLR, and FLRT1 before ordering.
- Measure the existing faceplate and wall opening.
- Check whether the customer wants a designer frame or a standard flush ring.
- Confirm finish and site appearance requirements.
Professional Advisory
For upscale entry columns or building lobbies, check the frame fit before final wall finishing. Rework around a telephone entry opening can be expensive after stone, stucco, or metalwork is complete.
Product Questions & Answers
What is the OPTDF1 used for?
It is an architectural designer frame for select SES telephone entry systems, commonly TEC1 HF and TEC1A applications.
Is OPTDF1 an electronic repair part?
No. It is a mounting and appearance frame only.
Is OPTDF1 the same as OPTDF2?
No. OPTDF1 and OPTDF2 are different SES designer-frame references and should be matched by model and dimensions.
Can this be used on CAT systems?
Some SES references show OPTDF1 around certain CAT/TEC examples, but the exact CAT faceplate and frame requirement must be verified before ordering.
What should I measure before ordering?
Measure the faceplate, opening, depth, and any existing trim so the frame matches the installed SES unit.
