Unico Universal Fixed Wall Mount Stand (14–55 inch) — which is likely what you mean by “UNICO WALL MOUNT 50 INCH 2R15 / 2R‑15” (or close model) — with its known specs and what to check:

✅ What it is / Key specs

• It is a fixed‑type wall mount (i.e. non‑tilting / non‑swivel) for mounting LCD/LED/Plasma TVs. 

• Supports TVs from 14 inch up to 55 inch. 

• Supports standard VESA mount patterns — from 75 × 75 mm up to 400 × 400 mm (or sometimes 100 × 100 mm depending on variant) — ensuring compatibility with most TVs including 50‑inch ones. 

• Constructed from galvanized / iron metal, giving decent structural strength. 

• Approximate dimensions: around 53 cm × 3 cm × 43 cm (for full 14–55″ variant) when flat. 

• The mount keeps the TV fairly close to the wall (i.e. low‑profile), which makes for a neat look. 

⚠️ What to check / Consider before using

• TV weight: Even though the mount supports up to 55", check that your 50" TV’s weight is within what the mount can safely hold. Heavy TVs may stress the mount or fixings.

• VESA compatibility: Ensure the mounting holes on your TV’s back match one of the supported VESA patterns (75×75 mm, 100×100 mm, 200×200 mm, 400×400 mm, etc). If they don’t match, the mount will not properly fit.

• Wall strength & installation quality: Being a fixed mount, proper installation — on a strong wall (concrete/bricks) with correct bolts/anchors — is important for safety and stability.

• Mount type constraints: As a “fixed” mount, it does not offer tilt, swivel or extend — so you will get a flush‑to‑wall installation but no angle adjustments.

🎯 For 50‑inch TVs — Is it suitable?

Yes — as long as your 50″ TV is within the supported weight and uses a supported VESA mount pattern, this Unico fixed wall mount is generally appropriate. The 14–55″ range and 75×75 – 400×400 mm VESA support makes it compatible with most 50″ TVs available.
