Pull-up Door Bar HMS DD301 with Triple Support — Adjustable Tension Mount for Home Pull-ups

HMS DD301 is a tension-mounted pull-up door bar engineered for home use and compact training spaces. The bar uses an adjustable tension system and a triple support structure to provide stability when installed in standard doorways or between parallel wall surfaces. Designed for pull-ups, hanging exercises and upper-body strength training, the HMS DD301 offers a non-permanent mounting solution that does not require drilling or fixed fixtures.

Advantages

The triple support design increases contact points and distributes load more evenly, reducing movement during use. The adjustable tension mechanism allows quick installation and removal while maintaining firm pressure against the doorway. Materials and construction provide a durable structure for repeated bodyweight exercises, and the compact form factor makes the bar suitable for storage when not in use.

Suitable for

• Home pull-ups and chin-ups
• Hanging leg raises and core conditioning
• Assisted calisthenics and upper-body strength training
• Short-term or temporary mounting in apartments and rented spaces

Key specifications

• Mount type: tension-mounted, no drilling required
• Support structure: triple contact points for increased stability
• Adjustability: tension adjustment to fit a range of doorway widths
• Use case: designed for bodyweight exercises such as pull-ups and hanging movements
• Storage: compact design for easy removal and storage

How to use

Measure the doorway or wall distance to confirm the bar fits the intended location. Extend the bar and position it between the two surfaces according to the manufacturer’s alignment guides, then tighten the tension mechanism until the bar holds firmly against both sides. Test stability with a light pull before performing full-bodyweight repetitions. After use, loosen the tension and remove the bar for storage or relocation.

Usage recommendations

Use the HMS DD301 only on sturdy door frames or walls rated to support user weight and follow weight limits and safety instructions supplied with the product. Inspect contact surfaces for damage and ensure even tension across supports before each session. Avoid use on fragile molding, hollow or weak doors. For controlled progression, combine pull-up variations with core and shoulder-strengthening exercises.
