7.5 Inch 18lb/80N Gas Strut Shock Spring Lift Support for

AUCLIDIS 7.5-inch, 18lb/80N gas strut is a direct replacement lift support for Sentry Safe lids that restores smooth opening and controlled closing for models using QAP1BE or QAP1BLX style cylinders.

If your Sentry safe door feels heavy, slams shut, or the original hydraulic lift has lost pressure, this AUCLIDIS replacement strut matches factory dimensions and force to return consistent performance. Designed to be a one-for-one substitute for QAP1BE and QAP1BLX style parts, the unit is built for straightforward installation and long-lasting function.

How will this gas strut affect the operation of my Sentry safe lid?

Installing this gas shock rebalances the lid so it opens smoothly and stays supported at intermediate angles instead of dropping. The 18lb/80N force provides gentle lift assistance while preventing sudden slams.

• Restores controlled opening and closing and reduces wear on hinges
• Prevents lid from slamming, improving safety and convenience
• Matches original extended and compressed ball-to-ball dimensions (7.68" / 5.70")

Is this AUCLIDIS strut compatible with my Sentry safe model?

This strut is specified to replace Sentry OEM parts QAP1BE, QAP1E and QAP1BLX; confirm compatibility by measuring your existing cylinder and checking the force rating. Compatibility is determined by model, OE number and the ball-to-ball lengths.

• Extended length (ball center to ball center): 7.68 inches
• Compressed length (ball center to ball center): 5.70 inches
• Force: 18lb / 80N — suitable for lids originally fitted with this rating

How do I install the replacement gas lift and what comes in the package?

Installation is typically a simple two-ball-socket swap: remove the old strut from its ball studs and snap the AUCLIDIS unit into place. The package includes the strut and one spring; no special tools are usually required beyond a flat screwdriver or pliers for retaining clips.

• Package contents: AUCLIDIS replacement strut ×1 and spring ×1
• Installation: remove old cylinder, verify ball stud alignment, snap new ends onto studs
• Tools: basic hand tools may be helpful for removing retaining clips

How should I choose the correct replacement if I'm unsure about measurements?

Start by comparing the OEM interchange number printed on your old cylinder; if that’s not available, measure ball-center-to-ball-center lengths when fully extended. Also match the force (18lb/80N) so lift assistance is equivalent to the original.

• Check old cylinder for OEM number like QAP1BE, QAP1E or QAP1BLX
• Measure extended length from ball center to ball center (should be ~7.68")
• Confirm force rating (18lb/80N) for similar lift performance
