Gemini Track, Push Up Drop Down Sign Letter Track for .060–.080 Rigid Letters, Clear Acrylic, Made in USA

Gemini Track Push Up Drop Down Sign Letter Track for Rigid Letters

Push up drop down track, sometimes called Gemini track or PUDD track, is the clear plastic rail system that holds .060–.080 rigid marquee letters on commercial changeable copy signs. This is the track used on many church, school, theater, and chain store readerboards where the letters are changed from the ground with a telescoping letter changing pole.

Each section is a clear extruded acrylic dual track that serves as the track face for your rigid letters. Track sections are made in the USA and typically available in 8 ft (96") and, when in stock, 10 ft (120") lengths. Only sizes that are currently available will appear as options in the size dropdown. Track can be trimmed to fit your cabinet and used as both the upper and lower track for each row of letters.

How Push Up Drop Down Track Works

Push up drop down track uses a dual rail profile that allows rigid letters to be pushed up, tipped into place, and dropped down into the track. On overhead signs, a telescoping letter changing arm with a suction cup is used to lift, move, and place each letter from ground level. This is the standard track system used by professional sign companies and commercial sign builders for permanent marquee and readerboard signs that need to be updated safely without a ladder.

Compatible Letters

This Gemini-style track is designed for .060–.080 rigid plastic letters, including:

• Rigid acrylic marquee letters
• Gemini Pronto rigid letters
• Other Zip Change style rigid letters made for push up drop down track systems

All major rigid letter brands use the same basic push up drop down track style, so compatible letters can be used together on the same sign. If you are not sure which type of letter your sign uses, see our guide for determining the correct letter type and size for your sign .

When to Choose Push Up Drop Down Track vs Flex Track

Choose Gemini-style push up drop down track with rigid letters if:

• Your sign is an overhead wall or pole-mounted marquee sign
• You change letters with a telescoping letter changing pole
• You use (or plan to use) .060–.080 rigid letters, Gemini Pronto, or Zip Change letters

Choose flex letter track (Texas track) and flexible letters if:

• You have a portable sign, ground-level readerboard, or sidewalk sign
• You change letters by hand at ground level
• You use thin .020–.030 flexible plastic letters

For flexible systems, see our flex letter track for .030 flexible letters and our flexible sign letter sets.

Installation

Gemini-style dual track sections can be installed directly to your sign face. Common attachment methods include:

• Mechanical fastening: Drill mounting holes through the track and fasten using stainless screws or nylon rivets.
• Adhesive bonding: Many sign shops use Weld-On or similar acrylic adhesive to bond the track to acrylic or polycarbonate faces. Adhesive bonding creates a permanent bond and usually cannot be removed without damaging the sign face or substrate.
• Trimming: Track sections can be trimmed to length with a fine-tooth saw to fit shorter cabinets or custom sign widths.

Nylon rivets for mounting sign letter track are sold separately.

Important Compatibility Notes

• Use this track with .060–.080 rigid letters only.
• Compatible with Gemini Pronto, Zip Change, and other rigid marquee letter brands made for push up drop down track.
• Not for flexible letters or Texas track systems – flexible letters will not seat correctly in this track.
• Most overhead wall or pole signs changed with a letter change pole require this style of push up drop down track and rigid letters.
